In Wisconsin minks, the platinum color of the fur is due to the P gene, in Oregon minks – the D gene, the recessive p and d genes also determine the platinum color of the fur. Brown (standard) coloration appears only if the genotype contains two dominant non-allelic PhD genes. What is the likelihood of platinum minks occurring if heterozygous brown minks are crossed?

The likelihood of platinum minks appearing if diheterozygous brown minks are crossed is 7/16.
