population genetics
... The way a trait is determined by the alleles for a gene depends on how the alleles, and the proteins they make, interact with each other. Obviously, if an individual is homozygous for a gene/locus (i.e., having two of the same allele), that allele determines the trait. If an individual is heterozygo ...
