Final answer:
When mating a chinchilla (cch c) rabbit with a grey (cg c) rabbit, the predicted outcome is grey offspring due to the assumption that grey is dominant over chinchilla. This follows the dominance hierarchy of rabbit coat color alleles, where wild-type is most dominant, followed by chinchilla, Himalayan, and albino, respectively.
Step-by-step explanation:
In the scenario provided, we are predicting the outcome of matings between chinchilla (cch c) and grey (cg c) rabbits, assuming multiple alleles influence coat color in rabbits and that the grey allele is recessive to the wild-type but dominant to chinchilla. Chinchilla rabbits have a genotype of cchcch, which results in black-tipped white fur, whereas grey rabbits have the cg c genotype. If grey is indeed dominant to chinchilla, then the offspring from a chinchilla and a grey rabbit would likely have the genotype cch cg, expressing the grey phenotype since cg is dominant over cch.
The dominance hierarchy for rabbit coat color alleles is C+ (wild-type) > cch (chinchilla) > ch (Himalayan) > c (albino). Given the information, the outcome of the mating between a chinchilla (cch c) and a grey (cg c) rabbit would result in a phenotypic ratio of grey rabbits, since grey is dominant over chinchilla. It should be noted that without knowing the exact dominance relationship between cg and cch, this prediction is based on the hypothesis that grey is dominant over chinchilla.
