n some breeds of dogs, a dominant allele controls the characteristic of barking while trailing. in these dogs, an allele of another independent gene produces erect ears; it is dominant over the 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:

To produce a pure-breeding strain of droop-eared barkers, the dog breeder should select dogs that have the dominant allele for silent trailing and the recessive allele for drooping ears. He should then breed these dogs together to produce offspring with the desired traits. If the desired combination of traits is not present in the initial selection of dogs, then the dog breeder should continue to breed and select for the desired combination of traits until he has achieved the desired result.
