Answer to Question #270336 in Cell Biology for Lisa

Question

The Newcastle Hare also has a single gene responsible for ear erectness. The allele E is dominant and produces a protein resulting in an erect pointy ear, while the recessive form (e) results in the lack of this protein and drooping ears. If a droopy eared, hissing male mates with a female who is heterozygous for both traits, answer the following questions:

i. What is the probability that any offspring will have droopy ears? (Blank 1)

ii. What is the probability that any offspring will be both droopy eared and hissing? (Blank 2)

iii. What is the probability that any offspring will be erect eared screamers?

iv. What are all the possible genotypes for the progeny (list them)?

Answer 1

I) 1/3

Ii) 1/8
