HELP!!!!!!!! PLEASE!!!????????????

In rabbits marbled fur (M) is a dominant trait. The recessive allele (m) results in white fur. One rabbit heterozygous for marbled fur mates with a homozygous dominant rabbit, and they have baby rabbits.

Which best describes the baby rabbits?

Female Rabbit
M m
Male Rabbit M
M


A.
50% will be heterozygous, 0% will be homozygous dominant, and 50% will be homozygous recessive.

B.
50% will be heterozygous, 50% will be homozygous dominant, and 0% will be homozygous recessive.

C.
25% will be heterozygous, 25% will be homozygous dominant, and 50% will be homozygous recessive.

D.
50% will be heterozygous, 25% will be homozygous dominant, and 25% will be homozygous recessive.

The statement that best describes the baby rabbits from the cross of one homozygous dominant and one heterozygous rabbit is B.50% will be heterozygous, 50% will be homozygous dominant, and 0% will be homozygous recessive. In the cross of Mm and MM, the offspring will be as following: 2 MM and 2 Mm. So, half of them (50%) will be dominant homozygous and half of them (50%) will be heterozygous, which is the same as choice B.

On the off chance that the latent allele brings about white hide. One rabbit heterozygous for marbled hide mates with a homozygous predominant rabbit, and they have child rabbits. The one that best depicts the infant rabbits is letter D. The answer is D.
