“Cheetahs Are Extremely Inbred”: 50 Interesting Genetics Facts You May Have Missed At School Perhaps my favourite biology fact is about pharmacogenetics, how your genetics determines the efficacy of drugs on your system due to prevalence of receptors of different types that the drugs target to produce an effect:

"90% of drugs only work on 30-50% of the population."

I find it so truly wild. But most people I've talked to about it seem to agree that some drug or other doesn't work for them. This really highlights how much of a process finding the right drug for a person is.
I had a lecture on this in uni in about 2016 and it said the future of pharmacology is individual genetic screens for drug effectiveness meaning people don't have to keep trying different drugs until they find the one that works, you would be tested then your doctor would have that info.
I just hope it overcomes the pushback from Big Pharma in my lifetime cause it would be a true game-changer.

“Cheetahs Are Extremely Inbred”: 50 Interesting Genetics Facts You May Have Missed At School There is a gene called TP53 - it’s referred to as the ‘guardian of the genome’ - it is a tumor suppressor gene and prevents cancer of all types. Humans have two copies and if one is broken/mutated it causes an inherited condition called Li Fraumeni. People with this have a very very high risks for cancer, and the condition can be passed down in families. Elephants have 20 copies of TP53 and therefore rarely get cancer. The Li Fraumeni foundation uses the elephant as its mascot and hopefully we can someday figure out how to replace faulty TP53 genes for these families.

While it might sound like a cross between dystopian fiction and body horror, some researchers believe that there is a lot of potential to store data and information in our DNA. After all, in one sense, that’s exactly what DNA’s actual function is. That being said, most of us probably don’t want to walk around with our own DNA turned into a sort of USB flash stick when we can literally buy this device in most stores.

Comically, as sci-fi as this idea sounds, it might already be out of date. Research into this topic has found that encoding data into our DNA is not only more costly but less reliable and slower to read than the various means of data storage we already have. So if you really want to get cyberpunk, perhaps get a QR code tattooed or investigate the wonderful world of chipping your palms.

That if you unraveled all of the DNA in your body, and stretched it out in a straight line, you'd be dead.

For simplicity, let's say your mother is 50% Chinese & 50% Spanish. That does **not** mean you are 25% of each.

On paper it would seem so but you can have any combination of those two equaling to 50%. It's not a clean cut in half. It's a *random* 50% given and 50% not. Although, yes there are dominate genes that can give all the kids a certain nose shape or eye color. Still, you and your siblings might get these DNA combos from mom:

- you: 30% C & 20% S

- brother: 12% C & 38% S

- sister: 5% C & 45% S

So if you ever wondered why your sister looks more Spanish than you its because genetics wise she just is more Spanish.

1. Most genetics studies were, and are still, done on white western populations. Some things that we "know" about genetics turn out to not work so well in non-white or non-western populations. Loose example: diagnostic tests to check for certain diseases sometimes misdiagnose Americans with African ancestry, because sometimes we don't actually know exactly how certain diseases will look in non-European ancestry patients, we just assume it will be the same.

2. Africa, as a whole, is the most genetically diverse continent for human genetics. Humans outside of Africa went through a population bottleneck, resulting in an overall lack of diversity moving forward. The human blender of genetics in Europe just didn't have many starting ingredients. There are things called linkage disequilibrium maps, which basically map out sections of the genome that are usually found inherited together. In Europe, these maps are quite "chunky", with large identifiable sections that are sort of reliably found intact. But in Africa, the blender was always running and never had a bottleneck, so those maps are basically a much finer puree, with a lot more mixing. This presents certain challenges, as many studies rely on those maps to make predictions, and it's harder to do that when the map for Africa as a whole is basically way more complex.

3. Everyone's cancer is its own unique genetic disease. There is no one true single disease called "lung cancer", just as there is no one single true human genome. Everyone is genetically unique (yes even identical twins), and every cancer is unique.

4. Chromothripsis is a thing where a chromosome pretty much shatters and gets stuck back together all out of order. And... this is sometimes okay. There are cases of people who have chromosomes that have undergone chromothripsis, and they have mild to moderate symptoms, but they're not dead, which is miraculous.

5. Remember in biology class when you learn about mitosis? And there's that step called metaphase where all the chromosomes line up in a line before being separated into two new cells? That spot in the middle of the "X"-shaped chromosomes where the spindles attach to line them up is called the centromere. And it's sort of mysterious black hole of genetics. There aren't usually any genes there, just a chaotic cluster-f**k of repetitive sequence that gets chopped forwards, backwards, repeated 7 times, swapped around and repeated again, etc etc in an area that's hundreds of thousands of nucleotides long. But what's even crazier is that we don't really know *why* they are how or where they are, because *you don't need the wacky wasteland of repeats for them to work*. Almost all centromeres in all animals look like this, but there are exceptions. A very notable exception is that very very rarely in humans, a "mar-del" chromosome can form where a chromosome accidentally loops on itself and pinches (think of that heart thing people do with their thumb and forefinger), resulting in a circular chromosome that still has its centromere, and a "butterfly" chromosome that does not. Without a centromere, a chromosome can't be duplicated into daughter cells successfully, and cells can't live without the genes on that butterfly chromosome so this should be lethal if it happens early on in development. But surprise, a centromere can and has spontaneously formed on the butterfly chromosome, making them tiny, viable chromosomes that work pretty much fine! But like I said this is super rare, with only a few recorded cases ever. Centromeres in general are very cool and very mysterious.

6. Everything about modern next-generation genetic sequencing is super interesting, yet not well known to the general public. I won't brain dump about it, but if you want to know more, ask and I will!

Also, pedigree collapse: no living person has as many unique ancestors as they mathematically should.

When you’re pregnant, bits of DNA from your baby invade your body and settle all over permanently - including in your brain. Researches found this by looking for male DNA in the brains of deceased 70 year olds. Interestingly, mouse studies have also shown that fetal cells within the mother have restorative properties and will rush to places like the heart, kidneys, lungs, liver if it’s injured and can even become cells that begin beating. One of the theories I have seen but I don’t know if anyone knows for certain if this is true is that these cells enter our bodies so a ‘host’ is less likely to reject the parasite baby.

I'm a geneticist with a mediocre master's degree in biology and currently pursuing a PhD in Bioinformatics. Here are some insights:

1. The accuracy of consumer and clinical genetic tests is often questionable due to the rapid pace of scientific advancements outpacing their application in the industry. The notable exceptions are information about Neanderthal ancestry (which is significant enough to have earned a Nobel Prize in Medicine) and a few critical mutations like the sickle cell variant and others related to blood.

2. Genetically, most humans are nearly identical, with differences being incredibly minute. This means that, barring age and sex, achieving success in various fields – whether it's social, intelligence, or physical appearance – is possible without genetic modifications.
Everyone likely has a unique genetic trait that gives them a significant advantage, however. This is currently identifiable only in a lab setting. Understanding your unique trait, which often involves the expression of certain molecules, might require professional scientific interpretation.

3. Many severe genetic diseases, such as insulin-dependent diabetes, are only about 50% determined by genetics. Factors like early developmental conditions, including a mother's diet during early pregnancy and infections, play a paramount role.

4. Despite common belief, Neanderthals were not a separate species but rather a part of the human family. For perspective, Europeans and the Khoisan people of South Africa have been genetically divergent for about 300,000 years, not much less than the 500,000-year divergence between humans and Neanderthals.

5. Factors beyond genetics, such as living in a highly controlled environment (like a prison), having access to specific nutrition, owning a car and a separate house, and engaging in mental activities like language learning, math, statistics, and team video games, can significantly impact personal development. Genetics helps us understand and appreciate the influence of these non-genetic factors.
The field of genetics is incredibly dynamic and continually evolving, offering many more fascinating insights.

“Cheetahs Are Extremely Inbred”: 50 Interesting Genetics Facts You May Have Missed At School Genetic chimera is arguably the most interesting condition. It is possible (and documented) for a woman to give natural birth but the baby not match her DNA test.

Essentially, 2 fertilized eggs merge at a very early stage and developing into a single organism. Different parts of the body comprised of obe or the other genome.

It's most commonly discovered in domestic animals that have unexplainable color combinations, often (but not always) divided symmetrically.

It happened to one woman. She almost had her child taken away from her because their DNA was different. It was only after she became pregnant again and gave birth, with DNA testing done immediately, that it was discovered she had genetic chimera and absorbed her fraternal twin during their embryonic stage of development.

Trauma can be inherited (look up transgenerational trauma).

So if you feel more sensitive than most people it might be because your grandma experienced something horrible.

On average it takes three generations to heal a trauma if I remember correctly. But only if properly treated and the parents do not retraumatize their kids with their unconscious trauma-responses. This way unhealthy behaviors would become the norm and eventually become genetically preferred automatic behavior for future generations.

A) As discussed above, hair can be affected by hormones. B) Pregnancy doesn't 'alter your DNA.' What happens, basically, is that the baby's cells enter your bloodstream through the placenta and some of the genetic material is incorporated into your own cells, which seems to particularly have an effect on the immune system - hence, possible new allergies. The mother's DNA hasn't been changed.

There is a list, check 23 and Me’s article The truth about biological sex. Here is a snippet, read the whole article for context. Generally, people with no Y chromosome appear biologically female, while people with at least one Y chromosome appear male: Most females are XX, and most males are XY. But there are other combinations too, such as XXX, XXY, XYY, XYYY, XXXY, XXXX, X (also known as XO),and mosaic XY/X or XX/X individuals, whose unusual karyotypes arose from a failure of sex chromosomes to end up in the right place during cell division. (A karyotype is the number and appearance of your chromosomes under a microscope.) But, biological sex isn’t all about which sex chromosomes you have.

I remember learning that from “Dead to Me”. Two of the characters were semi-identical twins and I thought, that sounds so fake.
