In mink, standard color (C) dominates over white (albino-c). It is required to establish: A) what offspring will appear when a homozygous standard mink is mated with an albino mink; B) what genotype and phenotype is expected for offspring when an albino mink is mated with a standard, heterozygous allele of white color.

According to the designations introduced in the problem statement, we write down the genotypes of the parent minks.

The standard mink that is homozygous is CC, it produces C.

An albino mink will be cc, because homozygosity is a prerequisite for the development of this trait. The reproductive cells produced by her body are of the same type – p.

The standard color of the heterozygote will be Cc, it produces two types of germ cells – C and c.

A). SS + ss. The offspring will look like: Сс, standard color – 100% cubs;

B). Ss + ss. Offspring: cubs of standard color (Cc) – 50%; albino cubs (ss) – 50%.
