Question

A male rabbit with genotype GgBb x with a female rabbit with genotype ggbb. Set up the Punnett square and determine the expected offspring and their proportions.

Answer 1

Answer:

25% all with genotype;  GgBb, Ggbb, ggBb, ggbb.

Explanation:

1. Male rabbit genotype = GgBb;

so,gametes are; GB, Gb, gB, gb

female rabbit= ggbb

so, gametes are; gb  all.

2. Cross between these rabbits = GgBb× ggbb

Punnett square;

                        GB   Gb   gB    gb

cross with       gb

3. So, progeny are GgBb, Ggbb, ggBb, ggbb

So, all  genotypes are 25%.
