Anth 121: Human Origins and Variation Laboratory 3. (5 pts) In a population of 10,000 individuals, 36 infants are born each generation with the recessive, lethal Tay-Sach's disease. This is a rare genetic disease found in highest frequency among Eastern European Jewish populations and is lethal within the first few years of life. A simple blood test is available to determine whether an individual is a carrier of the Tay-Sach's allele. It is harmless in the heterozygous condition, but lethal in the homozygous recessive condition. Calculate the number of individuals in this population that are Tay-Sach's carriers. 4. Recent genetic research has revealed a higher than expected frequency of Tay-Sach's carriers in French descended communities in Quebec and French descended communities in New Orleans. Can you construct a plausible explanation for these results?
