The length of the ears in rabbits of the Ram breed is 28 cm, in other breeds – about 12 cm. Suppose that the differences in the length of the ears depend on two pairs of genes with a unique cumulative effect. The genotype of rabbits of the Ram breed is D1D1D2D2, of common breeds – d1d1d2bd. Consequently, each dominant gene increases the length of the ears by 4 cm. What is the probability of the birth of rabbits with ears of 20 cm from the crossing of a female rabbit of the Ram breed and a male with 16 cm ears?
The probability of the birth of rabbits with an ear length of 20 cm from crossing a female rabbit of the Ram breed and a male with an ear length of 16 cm is 50%.
