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
