A species of mice can have long or short tails. If you crossed a male mouse which is heterozygous and has a long tail with a female mouse with a short tail, what would the expected phenotypic outcome be and why?

A)
100% long tails due to the Law of Dominance.

B)
There is no way to predict the phenotypic ratio since one of the parents is heterozygous.

C)
75% long tails and 25% short tails because the dominant allele for long tail still masks the recessive short tail allele.

D)
50% long tails and 50% short tails because the heterozygous genotype increases t
