The trait for 'black feet in ferrets' is a recessive trait encoded for by "f". White feet is encoded for by a dominant allele encoded for by the letter "F".

An ecological study in ferret country conducted by Mrs. Wright found that out of 1000 ferrets:

360 had black feet
480 had white feet and were heterozygous
160 had white feet and were homozygous.

Using this information find the allele frequencies for F and f.

Remember "F" = p and "f" = q

a
F = 0.4 and f =0.6
b
F = 0.7 and f = 1
c
F = 1 and f =0.7
d
F = 0.7 and f =0.3
