In the multiple-allele series that determines coat color in rabbits, c+ encodes agouti, cch encodes chinchilla, and ch encodes himalayan. dominance within this allelic series is c+> cch > ch. in a cross between c+/ch and cch/ch, what proportion of progeny will be chinchilla?

1/4

Explanation:

Dominance within this multiple-allele series is c+ (agouti) > cch (chinchilla) > ch (himalayan).

A cross between c+/ch x cch/ch  was done.

The possible genotypes of the offspring are:

So 1/4 of the progeny will be chinchilla.

there's no big difference.

explanation:

the only little different between a rabbit and bunny is just that bunnies are much smaller than rabbits. bunnies are basically baby rabbits.
