Question

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

Explanation / Answer

A. Himalayan 1 - chca

Himalayan 2- chca

1×2- chch, 2 chca, caca so will get one offspring as albino.

B. Full color - Ccch

Albino - caca

When crossed -2 Cca, 2 cacch

C. caca × cacch

2 cacch, 2 caca

50%albino and 50% chinchilla.
