Record the results of crossing two guinea pigs – a black (Aa) male with smooth (cc) hair with a white (aa) female, with wavy (Bb) hair

According to the condition of the problem, the black trait is dominant over the white color, and the wavy coat is dominant over the smooth coat (this conclusion is based on the genotypes of the parents).

Male – Aabb forms two varieties of gametes (sex cells): “Ab” and “ab”;

Female – aabb – two varieties of gametes: “aB” and “ab”. The result of the cross is shown in the Pennet lattice:

Gametes aB ab Ab AaBb

black wavy

Aabb

black smooth

ab
aaBb

white wavy

aabb

white smooth

That is, the result is possible in the ratio of both genotype and phenotype: 1: 1: 1: 1.
