A black guinea pig crossed with an albino guinea pig produced twelve black offspring. when the albino was crossed with a second black animal, six blacks and six albinos were obtained. what is the best explanation for this genetic situation?

I think the best explanation for this genetic situation would be that Albino is recessive and black is dominant. In genetics, a trait that will appear in the offspring if one of the parents contributes it. The relationship between alleles of one gene, in which the effect on phenotype of one allele masks the contribution of a second allele at the same locus. The first allele is dominant and the second allele is recessive. In this case the black color is dominant over the albino trait.
