The allele for the hair pattern called widows peak is dominant over the allele for no widows peak. In a population of 1000 individuals, 510 show the dominant phenotype. How many individuals would you expect of each of the possible three genotypes for this trait?

510 individuals have a widows peak and there would be 2 possibilities. Everyone with a widows peak would have either the WW or Ww genotype. There would be a 25% chance of WW and a 25% chance of Ww. The other 490 people do not show the dominant phenotype meaning all of them share the genotype ww. This means there is a 50% chance of the ww genotype.

WW: 25% Chance
Ww: 25% Chance
ww: 50% Chance
