Q. An inversion heterozygote possesses a normal chromosome and one with an inversion. The gene orders in these 2 chromosomes are shown below- Normal 1 2 3 4 5 6 7 8 9 10 o. The "o" denotes the centromere. Inverted 1 2 3 9 8 7 6 5 4 10 o. Represent the structure of chromosomes after meiosis given the follow events-
(a) A single crossover between genes 6 and 7.
(b) A 2-strand double crossover with one crossover between genes 4 and 5 and one between genes 7 and 8.
(c) A 4-strand double crossover with one crossover between genes 4 and 5 and one between genes 7 and 8.
