Q1. A female rat that is heterozygous for an autosomal reciprocal translocation has 36 eggs that were generated from following 9 meioses: 4 by alternate segregation, 4 by adjacent-1 segregation and 1 by adjacent-2 segregation. She is mated to a chromosomally wild-type male. What is the possibility that her offspring will inherit a chromosome bearing the translocation?

Q2. In a population with two alleles, A and a, frequency of A is 0.2. Organisms that is homozygous for A die before reaching sexual maturity. In five generations, what will be the frequency of individuals aa with genotypes?
