Question

Short Answer 28. Given the following information: Tall (T) is dominant over short (t), brown hair (B) is dominant over red hair (b), and a great sense of humor (H) is incompletely dominant over a being not funny (h). (Note: the inheritance patterns described are not factual!). The following cross is performed: Dr. Peter Linder (TtBbHH) x Dr. Carol Linder (TTbbHh) a. What is the probability that at least one of their children will be of tall, red- haired and be able to tell the funniest joke of the night? (2 pts). 76 25 -Ille (0) 4.920 b. What is the probability that both of their children will be tall, red-haired, and tell a joke that gets some laughs? (2 pts) -12 1/32 c.

Assume that long ear lobes in humans are an autosomal dominant trait that exhibits 50% penetrance. A person who is heterozygous for long ear lobes mates with a person who is homozygous for normal ear lobes, what is the probability that their first child will have long ear lobes? (2 pts) (0.540,5) = 25 25% Good 50. In cats, curled ears result from an allele (Cu) that is dominant over an allele (cu) for normal ears. Black color results from an independently assorting allele (G) that is dominant over an allele for gray (g). A gray cat homozygous for curled ears is mated with a homozygous black cat with normal ears. All the F1 cats are black and have curled ears. a. If two of the F1 cats mate, what phenotypes and proportions are expected in the F2?64 pts) A Cu6 -> this is FI An Feat mates with a stray cat that is gray and possesses normal ears. What phenotypes and proportions of progeny are expected from this cross? (4 pts) no Cucu
