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.
