1. Given a pericentric inversion heterozygote with one chromosome in normal order (1 2 3 4.5 6 7 8) and the other in the inverted order (1 5.4 3 2 6 7 8), diagram the first anaphase figure after a four-strand double crossover occurs: one crossover involves the regions between 4 and the centromere (.); the other crossover occurs between the centromere and 5.

2. A four-strand double crossover occurs in an inversion heterozygote. The normal chromosome order is (.1 2 3 4 5 6 7 8); the inverted chromosome order is (.1 2 7 6 5 4 3 8). One crossover is between 1 and 2 and the other is between 5 and 6. Diagram and label the first anaphase figures.
