Is curly hair in humans a mutation?
There is no single curly hair gene, and there is no way to genetically alter the presence of curly hair. Curly hair is not a defect, as its presence in geographically and ethnically disparate populations all over the world suggests that it certainly has its advantages, evolutionary and otherwise.

Where does the curly hair gene come from?
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.
Is curly hair common in India?
Even though 60\% of the world’s population has either curly or wavy hair, Indians have always considered straight hair the ideal type. Angela Vaz had to wear a wig at her wedding three years ago to hide her curly hair. The freelance illustrator from Bengaluru was always told to fight it, not flaunt it.
Can curly hair go straight?
Straight, sleek hair makes quite a statement, and with a little effort (and a lot of patience!), it’s totally doable. Depending upon how tight your curls are, you can go from curly to smooth in no time. Curly hair is naturally dry and prone to damage, so straightening your strands needs to be done very carefully.
Is straight hair a new trait in human evolution?
Straight hair seems to be a new trait in human evolution. It is associated with the newly emerged alleles in both the TCHH gene and EDAR gene.
Did our ancestors have curly or straight hair?
Straight hair seems to be a new trait in human evolution. It is associated with the newly emerged alleles in both the TCHH gene and EDAR gene. The distributions of these straight hair related alleles (see figure) support the hypothesis that our human ancestors had curly hair;
Is curly hair a dominant or recessive trait?
Same for the genes which control eye color and hair color: (Blonde and Red hair is recessive, as is Blue, Green, and Gray eyes). Note: The trait for Curly/Kinky hair (which is the “Normal” for humans): is produced by two “Undamaged” TCHH genes. That means that “Curly Hair” is “ANCESTRAL” to Modern Humans.
What gene is responsible for curly hair in Caucasians?
However, a single gene has yet to be found to be solely responsible for the curly (or straight) hair trait in Caucasians. A recent genome wide association scan has found a SNP (single nucleotide polymorphism) called rs11803731 in the TCHH gene which accounts for about 6\% of hair curliness.
