In hippos, addiction to beer is a dominant trait, while genes for green and white coloration are incompletely

In hippos, addiction to beer is a dominant trait, while genes for green and white coloration are incompletely dominant: heterozygous individuals are colored light green. crossed diheterozygous hippos. What is the likelihood that F1 offspring will have a white color and a love of beer.

Scheme for solving the problem:

A – love for beer, and – indifference to beer;

B – green, b – white. Вb – light green color.

Parents: AaBb x AaBb,

Gametes: AB, ab, Ab, ab x AB, ab, Ab, ab.

Offspring:

AABB, AaBb, AABb, AaBB,

AaBb, aabbb, Aabb, aaBb,

AABb, Aabbb, AAbb: AaBB,

AaBB, aaBb, AaBb, aaBB.

The offspring with white color and love for beer correspond to the genotypes Aabb and AAbb. Out of 3 out of 16, i.e. the probability is 3:16 or 18.75%.
