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)?

Zucchini has three autosomal genes that exist on three separate homologous pairs of chromosomes. Each is completely dominant over its recessive form. Here they are:

A = curly shape    B = green color      D = spotted

a = straight shape    b = yellow color      d = unspotted

* Figure out the probability of progeny with curly, yellow, spotted zucchinis arising from the cross of parents with the following genotypes:

   AaBbDd X AAbbDd      Probability = _____________
