Question

You have found a population of wild rabbits with a uniform grey coat color. You suspect that the grey allele is recessive to normal coat color and dominant to chinchilla. Predict the outcome of the following matings if your hypothesis is correct.

Chinchilla (cch c) x Grey (cg ch)

Answer 1

If the grey allele is recessive to normal coat color and dominant to chinchilla, the outcome of the mating between a Chinchilla and a Grey rabbit would produce offspring with a grey coat color.

Step-by-step explanation:

If the grey allele is recessive to normal coat color and dominant to chinchilla, the outcome of the mating between a Chinchilla (cch c) and a Grey (cg ch) rabbit can be predicted. The Chinchilla rabbit has the genotype cch c, where c is the chinchilla allele and ch is the normal coat color allele. The Grey rabbit has the genotype cg ch, where cg is the grey allele and ch is the normal coat color allele.

According to the provided information, the grey allele is recessive to the normal coat color allele and dominant to the chinchilla allele. So, if the Grey rabbit is crossed with the Chinchilla rabbit, the possible genotypes of the offspring can be cg cch or cg c. Since the grey allele is dominant to the chinchilla allele, the offspring will have a grey coat color.

Therefore, if the hypothesis is correct and the grey allele is recessive to the normal coat color allele and dominant to the chinchilla allele, the outcome of the mating between a Chinchilla (cch c) and a Grey (cg ch) rabbit would produce offspring with a grey coat color.
