An inversion heterozygote possesses a normal chromosome and onewith 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 thecentromere.)
Inverted 1 2 3 9 8 7 6 5 4 10 o .
Draw the structure of the 4 strands (chromosomes) after meiosisgiven the following events-
(a) A single crossover between genes 6 and 7.
(b) A 2-strand double crossover with one crossover between genes 4and 5 and one between genes 7 and 8.
(c) A 4-strand double crossover with one crossover between genes 4and 5 and a second one between genes 6 and 7.
