Mice can have BLACK (F) or WHITE (f) fur color. Mice can also have BLACK (E) or
RED (e) eye colors.

The heterozygous genotype for black fur is Ff.

The homozygous genotype for red eyes is ee.

The homozygous genotype for black fur is FF

Explanation: Heterozygous genotype means having a pair of gene containing one dominant allele and one recessive allele. There a heterozygous genotype for black fur will have one allele for black fur (F) and one allele for white fur (f) = (Ff)

A homozygous genotype is a pair of gene containing two identical alleles: either two dominant alleles or two recessive alleles. A homozygous genotype for red eyes will contain two recessive alleles for red eye (e) = (ee).

A homozygous genotype for black fur will contain two dominant alleles for black fur (F) = (FF).

the fossil record provides evidence of a common ancestor to many species.
