Asap indicate the coat color and the proportion of offspring with that color for each of the following crosses of rabbits. assume all are homozygous. alleles: a=agouti, c=chinchilla, a=albino, a is dominant over c and a, c is dominant over a agouti x chinchilla a) 1/2 chinchilla, 1/2 agouti b) 3/4 chinchilla, 1/4 agouti c) all agouti

Hi,

C) all agouti

Explanation:

As we know that dominance of alleles for the coat color in rabbits goes like this:

                                          C+ > Cch > Ch > C.

If we cross homozygous agouti  with homozygous chinchilla the cross will look like this:

P1:                                            agouti x chinchilla

P1:                                         C+C+        X   Cch Cch

F1:                                          C+Cch       :       C+Cch

Since C+ is dominant over Cch, it means that all the offspring will have agouti coat that makes option C correct.

Hope it help

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
