In chickens, the allele for feathered legs (F) is dominant over the allele for bare legs (f). In a population of chickens on a farm, 240 chickens have feathered legs
(FF or Ff), and 80 chickens have bare legs (ff). How many chickens can be
expected to be heterozygous for feathered legs (Ff)? Assume that the conditions
of Hardy-Weinberg equilibrium apply to the population
a. 160 c. 80
b. 200 d. 40
