Question

Some dogs bark while trailing, others are silent. The barking trait is due to a dominant gene. Erect ears are dominant to drooping ears. What kind of pups would be expected from a double heterozygous erect–eared, barker mated to a drooped–eared, silent trailer? What are the genotypes of the parents? Gene B controls the barking ability; gene E controls ear shape. (6 points) Let B be the dominant allele for the barking trait. Let b be the recessive allele for the silent trait. Let E be the dominant for erect ears. Let e be the recessive allele for drooping ears.

Explanation / Answer

Answer:

Double heterozygous parent (BbEe) x dreooped-eared, silen trailer parents (bbee)---Parents

be BE BE/be (barking, erect-eared)-25% Be Be/be (barking, drooped-eared)-25% bE bE/be (silent trailer, erect-eared)-25% be be/be (silent trailer, drooped-eared) 25%
