I have red hair which occurs naturally in only 1-2% of the human population
Uau, that is cool.You are an original person.
Yes!  I am !!  Red hair occurs in people of northern or western European ancestry.
So is it a genetic trait.Do you think there is a chance to pass this trait to your children?
It appears in people with two copies of a recessive allele on Chromosome 15, so yes it inheritable.
Tell me more about the genetic aspects of this trait, please.
Chromosome 16 with the alleles produces an altered version of the MC1R protien which gives hair a brownish hue (in other cases)
This topic is so complex and interesting.I wish i had study more when i was in high-school.
Go to college!  The term redhead has been in use since at least 1510
Really, that long?? It is a history thing then.
