Answer: 50% will have short hair

Explanation: The allele for a heterozygous dominant short hair is (Ss) and the allele for the homozygous long hair which is the recessive trait is (ss).

If we cross these alleles the results will be.

s s

S Ss Ss

s ss ss

The results will have 50% Heterozygous dominant short hair and 50% Homozygous recessive long hair.
