In the multiple-allele series that determines coat color in rabbits, c+ encodes agouti, cch encodes chinchilla, and ch encodes H imalayan. 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 answer:
Answer:
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.
<u>The possible genotypes of the offspring are:</u>
c+/cch: agoutic+/ch : agoutich/cch : chinchillach/ch: himalayan
So 1/4 of the progeny will be chinchilla.
