Genetic Variation facts

While investigating facts about Genetic Variation Examples and Genetic Variation Definition Biology, I found out little known, but curios details like:

There is rare genetic variation (SNP rs121912617) that allows people to sleep 2 hours less a night with no ill effects.

how genetic variation occurs?

Scientists have found that Ozzy Osbourne has unique genetic mutations that that increase his body's endurance for hard drugs and excessive alcohol: the "genes connected to addiction, alcoholism ... all had unique variations in Osbourne, a few of which geneticists had never seen before"

What genetic variations increase the risk of cardiovascular disease?

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what genetic variation in offspring. Here are 14 of the best facts about Genetic Variation In Meiosis and Genetic Variations In A Population Are Caused By Random I managed to collect.

what's genetic variation?

1. Genetic variations may make some people's brain more open to thoughts, sensations and behaviors that don't make it past the average person's mental filters. These same variations may also explain why many highly creative people seem eccentric at times—or even suffer from mental illness

2. Humans have a relatively low level of genetic variation because we are all descendants of ~10,000 humans that survived a massive extinction event ~70,000 years ago. One tribe y'all.

3. Many Asians get less alcohol "buzz" but quicker and more severe hangovers, due to a genetic variation where they metabolize alcohol more efficiently but not the toxic metabolite.

4. The current cheetah population was repopulated by less that 7 cheetahs 10000 years ago leading to very little genetic variation

5. 20% of people of European or African ancestry have a genetic variation that makes them almost immune to Norovirus (stomach flu)

6. There is more genetic variation within the African population than there is between African and Eurasian (full scientific report in comments).

7. For a portion of the world population, Cilantro tastes like soap due to a genetic variation.

8. Biological evolution is a form of trial and error; Random mutations and sexual genetic variations can be viewed as trials and poor reproductive fitness, or lack of improved fitness, as the error.

9. Future antidepressant drugs will account for individual genetic variations and will be tailored to the individual's genome to maximize drug response and to minimize side effects. The field of research that investigates genome-drug interactions in depression is called Psychopharmacogenetics.

Why genetic variation important for evolution?

You can easily fact check why genetic variation is useful by examining the linked well-known sources.

While our species is roughly 165K years old, and has been in Europe for around 50K years, the genetic variation associated with "white" skin color is only around 10K years old.

To many people, cilantro tastes like soap due to genetic variations allowing them to strongly perceive the soap-flavored aldehydes in cilantro. - source
