Please explain why.( really need this)


Which best describes the baby rabbits?



Female Rabbit
M m
Male Rabbit M
M



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

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

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

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

Answer 1

the answer is A. When you have MMxMm mating, half the offspring will have homo dominant genotype and the other half will have heterozygous genotype. You can draw the punnet square to help u understand it.

hope this helps:)
