Question

Albinism is an autosomal trait in rabbits. We have a P0 generation with the female rabbit pure breeding (homozygous) albino with the male rabbit pure breeding normal. They mate and produce several offspring, the F1 generation. The F1 generation is crossbred to create the F2 generation. Create reasonable genetic notation for each of the crosses and list them here.

- Female P0:

- Male P0:

- Female F1:

- Male F1:

Create the Punnett square for the F2 generation using a 3x3 box. Put the female gametes on the vertical side and the male gametes on the horizontal side. Give the chances for the individual genotypes and phenotypes.

F2 genotypes (with probabilities):

F2 phenotypes (with probabilities):
