1 A farmer has rabbits with two particular traits, each controlled by a separate gene.
Coat colour brown is completely dominant
to white. Tailed is completely dominant to
tail-less. A brown, tailed male rabbit that is
heterozygous at both loci is crossed with a
white, tail-less female rabbit. A large number
of offspring is produced with only two
phenotypes: brown and tailed, white and tail-
less, and the two types are in equal numbers.
