Inversion heterokaryotypes are often characterized as having reduced crossing over and reduced fertility
Assume that you were examining a strain of organisms you knew to be inversion heterokaryotypes and saw a relatively high number of double chromatid bridges extending between anaphase I nuclei. What would be a likely explanation for this observation? Explain with a labeled diagram.
A four-strand double crossover in the inversion loop of a paracentric inversion (in the heterozygous state) would generate the double bridge and two acentric fragments (which would be lost).
