5. Some dogs bark while trailing, others are silent.The barking trait is due to a dominant gene. Erect ears aredominant to drooping ears. What kind of pups would be expected froma double heterozygous erecteared, barker mated to a droopedeared,silent trailer?
Gene B controls the barking ability; gene E controls ear shape. LetB be the dominant allele for the barking trait. Let b be therecessive allele for the silent trait. Let E be the dominant forerect ears. Let e be the recessive allele for drooping ears.
