Suppose a Population of Worms Is Variable at a Genetic

Suppose a population of worms is variable at a genetic locus involved in foraging behavior. There are just two alleles at this locus, F and f. Individuals that are FF or Ff are rovers and will travel widely in pursuit of food. Individuals that are ff are sitters and will not travel as far. The frequency of the F allele is 0.75. The frequency of the f allele is _______ and, assuming the Hardy-Weinberg equation, the percentage of the population that are sitters is therefore _______.

A) 0.125; 50%
B) 0.25; 6%
C) 0.57; 33%
D) 0.75; 50%
