Two mice with white fur (ff) are bred. what will be true of the offspring?

question 2 options:

all of the offspring will be white.

three-quarters of the offspring will be white.

one-half of the offspring will be white.

all of the offspring will be black.

The correct answer would be - all of the offspring will be white.

Explanation:

Mice with white fur (ff) is homozygous recessive and its cross with other mice with white fur (ff) will have all offsprings with white fur with same genotype (ff) as there is no allele other than f in both parent mice so there is no chance of having any change in phenotype or genotype in offsprings.

The cross between :               homozygous X homozygous

                                                                        ↓

                                                               homozygous

Thus, the correct answer would be - all of the offspring will be white.
