Widows peak is dominant to no widows peak. Determine the genotype and phenotype ratios for a homozygous dominant female and a homozygous recessive male

All children will have genotype Ww and phenotype widow's peak.

Explanation:

Widow's peak (W) is dominant over no widow's peak (w). So,

WW, Ww = widow's peak

ww = no widow's peak

Female = homozygous dominant = WW

Male = homozygous recessive = ww

WW X ww:

W W

w Ww Ww

w Ww Ww

All the children will have genotype Ww and phenotype widow's peak.
