3.

Assume that in the U.S. in 1960, the frequency of the autosomalrecessive Tay-Sachs disease among eastern European Jews was 1 per3600births.

What was the frequency of the Tay-Sachs allel in thispopulation?

In 1961, a woman of polish ancestry whose brother died of Tay-Sachsdisease marries a Jewish man of Hungarian ancestry. Assuming thatshe is a carrier, what is the probability that their first childwill have Tay-Sachs disease?

4. In fruit flies, black body (b) is recessive to normal body color(B). In a breeding study, a population of flies is allowed to mateat random. In the population, 3000 flies are homozygous for blackbody color, and 2000 flies are homozygous for the normalallele.

What is the frequency of each genotype in the F1 generation?

What would the proportion of phenotpyes be?

What is the frequency of the two alleles, B and b, in the F1generation?
