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.
We call these genes the genome.
They don't express in heterozygous condition ,hence remain in gene pool .
gene pool
The Genetic variation between the organisms in the specific gene pool.
The split between 2 volcanic atoms that form when alleles break up and migrate to another gene pool.
1.Which does not add new alleles to a population gene pool?
The entire collection of genes among a population is called the "gene pool".

We call these genes the genome.
Each gene has a dominate and recessive allele, so there are two types of alleles in each gene. The dominate allele is stronger than the recessive allele unless there are two recessive alleles.
Gene pool. All the alleles of all the genes of a population make up a gene pool.
All of the alleles in one populationAll of the alleles in one population
It changes it by, generally, selecting out some alleles thus allowing other alleles to increase their numbers in the populations gene pool.
