WebMay 22, 2003 · Drosophila has cis- acting pairing centers (Hawley 1980 ), seems not to need double-strand–break repair to establish chromosome synapsis (Dernburg et al. 1998 ), shows strong interference (Foss et al. 1993; Zhao et al. 1995 b ), and seems to have only one recombinational pathway (Copenhaver et al. 2002 ). In genetics, the coefficient of coincidence (c.o.c.) is a measure of interference in the formation of chromosomal crossovers during meiosis. It is generally the case that, if there is a crossover at one spot on a chromosome, this decreases the likelihood of a crossover in a nearby spot. This is called interference. The coefficient of coincidence is typically calculated from recombination rates between three ge…
