Question

In some breeds of dogs, a dominant gene controls the characteristic of barking while trailing. In these dogs, another independent gene produces erect ears; it is dominant of its allele for drooping ears. Suppose a dog breeder wants to produce a pure-breeding strain of droop-eared barkers, but he knows that the genes for silent trailing and erect ears are present in his kennels. How should he proceed?

Answer 1

I belive that he should get more dogs of the droop ear barkers, mate them with the ones he has, and use the droopy barkers from the bunch to mate, and get more droopy barkers. or just get new dogs. (he cat still keep the current dogs)

Answer 2

can not cat
