Tay-Sachs is a recessive lethal disease in which thereis neurological deterioration early in life. This diseaseis rare in the population overall but is found at relatively high frequency in Ashkenazi Jews from EasternEurope. A woman whose maternal uncle had the disease is trying to determine the probability that sheand her husband could have an affected child. Her father does not come from a high-risk population. Herhusband’s sister died of the disease at an early age.a. Draw the pedigree of the individuals described.Include the genotypes where possible.b. Determine the probability that the couple’s firstchild will be affected.

Androgenetic alopecia (pattern baldness) is a complextrait in humans governed by several genes, but supposea human population exists in which a single autosomalallele determines pattern baldness.

42. Kermode bears are found in the central and north coastal regions of British Columbia. Although most Kermode bears have black coats, about 10% of the population have white coats like polar bears. This white coat colour is caused by two autosomal recessive alleles.What is the probability of two black Kermode bears having a male white cub?Answer(Record your answer as a value rounded to two decimal places.)

Cystic fibrosis (CF) is an autosomal recessive disorderthat occurs relatively frequently among people ofEuropean descent. In an Amish community in Ohio,medical researchers reported the occurrence of cysticfibrosis (CF) as being 1/569 live births. Using theHardy–Weinberg rule, estimate the frequency of carriers of the disease allele in this Amish population.
Some people can taste the bitter compound phenylthiocarbamide while others cannot. This trait isgoverned by a single autosomal gene; the allele fortasting is completely dominant with respect to the allele for nontasting. Among 1707 Hawaiians tested forthe ability to taste, 1326 tasters were found. Assumingthat the population is at Hardy-Weinberg equilibriumfor this gene and that mating is purely random:a. What are the allele frequencies for the tasting alleleT [= (p)] and for the nontasting allele t [= (q)]?b. What are the genotype frequencies in the population?c.
