In rabbits multiple alleles control coat color in the follow

In rabbits, multiple alleles control coat color in the following hierarchy: C (Full color)>c^th (Chinchilla) > c^h (Himalayan) > c^2 (albino). In the following matings, determine the genotype of the parents and the offspring. Himalayan-1 X Himalayan-2 resulted in one of their offspring being albino. Genotype Himalayan-1= Genotype Himalayan-2= Genotype F1 albino= Full color X albino resulted in one of their offspring being chinchilla. Genotype of Full color = Genotype of albino = Genotype of F1 Chinchilla = If the F1 albino from cross A was mated to the F1 Chinchilla of cross B, what offspring would be produce? F1 Albino X F1 Chinchilla

Solution

A. Himalayan 1 - c^hc^a

Himalayan 2- c^hc^a

1×2- c^hc^h, 2 c^hc^a, c^ac^a so will get one offspring as albino.

B. Full color - Cc^ch

Albino - c^ac^a

When crossed -2 Cc^a, 2 c^ac^ch

C. c^ac^a × c^ac^ch

2 c^ac^ch, 2 c^ac^a

50%albino and 50% chinchilla.
