Your question makes little sense. The allele for cytochrome C is in all human gene pools regardless of population variance. So is the allele for melanin, which has to do with skin tone. ( among other things ) Allele are just different molecular forms of the same gene. These are distributed through out human populations and some populations have a greater frequency of particular alleles. Remember, humans are a '' small '' species genetically, so even with covariance among populations, it would be difficult to find a '' black '' allele. Think sickle cell trait and see how many different types of humans posses this trait.
