Your parents provided one allele per gene at time of your conception (then these alleles paired to form your hair texture genes). It is the interaction among these alleles, not one specific gene, that determined the character of your hair.
Each parent has a role in providing an allele for every single gene. Your hair is the result of the interaction of your parents and does not depend on a single gene.
One popular myth is that hair loss in men is passed down from the mother's side of the family while hair loss in women is passed down from the father's side; however, the truth is that the genes for hair loss and hair loss itself are actually passed down from both sides of the family.
Both of your parents give you two pieces of genetic information, called alleles, that determine what your hair type will be. The two alleles from your biological father combine with two alleles from your biological mother, giving you four in all.
Curly hair is determined by factors you inherit from your biological mother and your biological father. There's no single gene that determines the way that your hair looks. The way your hair looks when you're born is also a clue into the genetic information you'd pass to your own children if you have them.
All men inherit a Y chromosome from their father, which means all traits that are only found on the Y chromosome come from dad, not mom. The Supporting Evidence: Y-linked traits follow a clear paternal lineage.
Unlike nuclear DNA, which comes from both parents, mitochondrial DNA comes only from the mother.
this actually goes back 35,000 years ago from a genetic mutation. the EDAR gene which is the gene that is responsible for developing the skin. was actually found to be mutated in Asians. this gene is responsible for making a protein that creates hair.
According to Personal Health via the New York Times, Caucasians are the hairiest ethnic group, with Semitic and Mediterranean people being the hairiest out of all Caucasians.
Baldness can of course skip generations! If you have bald relatives on both sides of your family tree the chances are high you will be too. However, if the baldness shows up only on one side, it's highly possible the MPB gene will skip not only you but also your siblings. This is how the recessive gene works.
It turns out that brown hair is dominant. That means that even if only one of your two alleles is for brown hair, your hair will be brown. The blond allele is recessive, and gets covered up. If two brunette parents have a blond child, they had to have instructions for making blond hair hidden in their DNA.
Caucasians have the highest hair density among the ethnicities studied. Black people have the lowest. Asian people have hair density that falls somewhere in between.
Caucasian, Asian and Indian hair samples were put to the test for the World's Best Hair study. Their results put an end to any splitting of hairs over the issue: in terms of health, the Indian hair is the best, topping other ethnic groups on all four counts.
Hair Growth Rate
Asian hair shows the fastest growth rate in comparison to the other two hair types. African hair has the lowest growth rate.
Many Asians have naturally straight hair, but there is a significant group of us who do have naturally curly or wavy hair! However, because it's the norm to see straight and sleek hair, curly haired boys and girls tend to think that their hair is some kind of unruly straight hair that isn't behaving.
Relevant paragraph from Wikipedia from the article on body odor below, but the TL;DR is that there's a gene called ABCC11 that is non-functional in 80 to 95 percent of East Asians. That allele determines both apocrine sweat gland size and activity, concentration of protein in apocrine sweat, and, oddly, wet-type vs.
It's thick.
The reason Asian hair tends to be thicker is that it has around 10 layers of cuticles. Cuticles are the small areas around the inner protein structure of your hair–they are there to protect those proteins.
Here's how that breaks down by gender: Girls receive an X-chromosome from each parent, therefore their X-linked traits will be partially inherited from dad, too. Boys, on the other hand, only receive a Y chromosome from their father and an X chromosome from their mother.
Each parent will pass one copy of their eye color gene to their child. In this case, the mom will always pass B and the dad will always pass b. This means all of their kids will be Bb and have brown eyes. Each child will show the mom's dominant trait.
DNA. Everyone knows that DNA is what determines your baby's appearance. But DNA is a very complex subject. Everything from hair color, eye color, height, and weight to the placement of dimples or freckles can be dictated by you or your partner's (or both!)
And while it is true that you get half of your genes from each parent, the genes from your father are more dominant, especially when it comes to your health.
Men pass only the Y chromosome to their sons. He will always (100% chance) pass on the gene that does not function properly to his daughters, because he only has one X chromosome, and he passes that X chromosome to all of his daughters.
There's no set genetic rule that all first born daughters look like their dads, but in many cases – thanks to TikTok – we've seen this theory proved. However, we think this is nothing more than a cute opportunity for Das to be involved with their daughters' TikTok careers.
Certain races have higher rates of hair loss compared to others. Caucasians have the highest rates out of all the ethnic groups. On the opposite end of the spectrum, Native American Indians, Inuits, and Chinese have the lowest rates. Let's dive in deeper.
