(a)
Deafness in cocker spaniels is inherited. The allele for deafness is recessive to the allele for normal hearing.
Two cocker spaniels with normal hearing are mated together. They produce a litter of eight pups, two of
which are found to be deaf.
(b)
(a) Give the genotypes of the parents. DDd x Dd 1
(b) Show the possible genotypes, phenotypes and probabilities for the offspring.

Having dimples (D) is dominant over not having dimples (d). A dimpled woman (whose father had no
dimples and whose mother did have dimples) marries a man whose mother had no dimples, whose father
had no dimples, and whose grandparents on his father's side did have dimples!
