29 Interesting Facts About The Genetics Behind Human Traits

I was very curious to learn more about the inspiration behind the super popular 'How rare are you?' videos. "My inspiration behind this series was to try to get people to embrace what makes them unique!" Lexi told Bored Panda. "I think it resonated with so many people because I tried to include many different things so that hopefully whoever was watching would be able to find something that they could relate to," she said she was as inclusive as she could be.

Bored Panda was interested to hear a bit about what it's like to have such a large following on TikTok. Lexi opened up that it's been a life-changing experience. "It has changed my life! It still shocks me that there are so many people who love and support me and care about what I have to say. It’s given me confidence in who I am and has made me a better person because I know that I have younger fans who look up to me and I want to be a good role model for them."

Lexi explained that she followed in the footsteps of her favorite creators and wanted to become a positive role model for others. "When I was younger, I watched a lot of YouTube videos and I had creators that I looked up to. Sometimes if I was having a bad day these videos were like an escape for me and they would cheer me up. I want to be that person for someone else," she said.

"My followers always suggest topics for me to make videos on and I try to listen to them as much as I can!"

Lexi is a force to be reckoned with on TikTok. She has a whopping 2.4 million followers on the platform. Meanwhile, she’s collected just shy of 100 million (that’s right!) likes on TikTok. That just goes to show that the content she creates and her personality shine through in the endless stream of videos on the platform.

The TikToker creates videos about fun facts (that's where her videos about genetic traits come in), does storytimes, shares various theories, and does a bit of everything else.

According to World Atlas, the vast majority of the world’s population has brown eyes. However, it’s incredibly difficult to pinpoint the exact number. The best guess is that anywhere from 70 to 79 percent of human beings have brown eyes. Meanwhile, from 8 to 10 percent of people have blue eyes.

Even rarer than blue eyes are hazel and amber eyes, with around 5 percent of the global population (that’s 1 in 20 people on the street) having them. Gray eyes make up barely 3 percent of the total while green ones make up only 2 percent. The rarest eye color is red/violet, with less than a single percent of people having such eyes. Similarly, less than 1 percent of people have heterochromia which means that both of your eyes are different colors.

The field of genetics continues to advance. Even facts that we took for granted (remember those biology lessons back at school) are now being updated and revised. For instance, scientists used to think that your eye color was determined by only two genes, one from each parent. You’re likely to remember doing some exercises in class where you’d see what color eyes a child would have if one parent has e.g. two dominant brown-eyed genes and one has recessive blue-eyed genes.

However, Healthline points out that we’re now aware that things are far more complicated. “Your eye color is determined by several genes that control melanin production in your iris. Darker eyes have a lot of melanin, while light eyes have only a little.”

Healthline explains that brown eyes look dark to us because they have a lot of light-absorbing melanin. Meanwhile, blue eyes have the least amount of melanin, so they reflect the most light. What this means is that reality isn’t as simple as what a lot of us were used to during biology class.

“Because you inherit genes from your parents, it’s likely that your eyes will be similar in color to one or both of your parents. But it’s also possible for you to have brown eyes, even if both of your parents have blue eyes.”
