What is the effect of a rare double crossover (a) within a. chromosome segment that is heterozygous for a pericentric inversion; and (b) within a segment that is heterozygous For a paracentric inversion?
HINT: Tins problem involves an understanding of how homologs synapse in the presence of a heterozygous inversion, as well as the distinction between pericentric and paracentric inversions. The key to its solution is to draw out the tetrad and follow the chromatids undergoing a double crossover.
