Yes but there are more genes than simply one for generating both blonde hair and blue eyes. The single mutation was found in a long gene sequence called kit the gene codes for a protein known as kit ligand, which binds to receptors throughout the body and affects pigmentation, blood cells, nerve cells. But that's the wrong for example, if your mom has red hair and your dad has black hair, chances are you're going to have black hair because the gene for that color is. 'the genes that affect hair colour also affect other cancer types, while other pigment genes affect the chances of having crohn's and other forms of bowel disease.' it is likely that hundreds of other genes also affect hair colour in ways that were too subtle for the scientists to detect.

Blonde hair is a recessive phenotypical trait, and it either appears relatively often or doesn't appear at all. They don't have enough of the recessive genes to have either blond or ginger hair, but they don't have a dominant gene to take charge?

The third has light brown/blond in summer wouldn't a recessive gene eventually drop out after not showing in a couple generations? Researchers found a genetic determinant of blond hair in solomon islanders. For example, the allele for blue eyes is recessive, therefore to have blue eyes you need to have two copies of the 'blue eye' allele. For the blonde gene to disappear, it would require that populations with a high proportion of blondes such as northern europeans reproduce much i don't know about blonde hair but in order to have light blue eyes a child needs four copies(alleles) of the gene responsible. Having blonde hair is a recessive trait meaning if a person has a gene for the blond haired brother had to have two recessive alleles (ex.
