Crossover gene conversion
WebJan 20, 2024 · Recent work demonstrates that, although recombination by single crossovers within inversions is almost entirely absent in Drosophila, a low level of recombination occurs in inversion heterokaryotypes, termed gene flux, through nonreciprocal, non-crossover gene conversion and double crossover events . WebOn the other hand, recombination between the two 99%-homologous genes (tufA and tufB), coding for EF-Tu translation elongation factor and present in the chromosomes of both E. coli and Salmonella, can go by either single crossover or by double crossover / gene conversion, because the two repeats are positioned almost symmetrically around the ...
