Question
The height of a rabbit's ears is a polygenic trait.
In one variety of rabbit, the ear length was 3
inches and in another variety of rabbit it was 11
inches. Rabbits pure for the trait of short ears (3
inches) were mated with those pure for the trait
for long ears (11 inches), yielding an F1 of
intermediate ear length of 7 inches. The F1 were
mated to each other and produced an F2
population, in which the 3 inch and 11 inch
appeared in a frequency of 1/256. How many
inches does each allele contribute to the length
of the rabbit ear?
