In dogs, there is a hereditary deafness caused by an autosomal recessive Gene,"d". A kennel owner has a male dog that she wants to use for breeding purposes if possible. The dog can hear. If the dog's genotype is Dd, the owner does not wish to use him for breeding so that the deafness gene will not be passed on. This can be tested by breeding the dog to a deaf female. Draw the Punnett squares to illustrate these two possible crosses. In each case, what percentage/ how many of the offspring would be expected to be hearing? deaf? How could you tell the genotype of this male dog? Also, using Punnett square (s) show how two hearing dogs could produce deaf offspring.
