Imagine that head shape is controlled by a maternal effect gene. The dominant h allele produces a oval-shaped head, while the recessive h allele produces a square-shaped head. Imagine that a woman has an oval-shaped head. Her father has the h h genotype. What proportion of head phenotypes do you expect to see in her children

Answers

The woman’s genotype is Hh because her father has the genotype hh. If the woman has children with a person who’s genotype is HH, you see 100% oval heads, you’d have genotype HH and Hh. If the woman has children with a person who is Hh, you expect 75% oval heads and 25% square heads with the genotypes HH, Hh, and hh. If she has children with some who is hh, you’d expect 50% oval, 50%square with genotype Hh and hh. To solve, use punnet squares!
