Albinism is a recessive trait. It is expressed only in an individual's genotype contains a pair of the recessive allele 'a', that is responsible for causing albinism.

Black skin color in guinea pig is a dominant trait which does not allows the recessive trait to be expressed.

Thus, guinea pigs having the genotype 'aa' will exhibit albinism while those having the dominant allele for black color will have black skin color.
