WebApr 1, 2002 · interference, p, was bounded above by ~0.25 and generally was close to 0.20. While the estimate did occasionally fall below 0.10 when two crossover pathways were simulated, the case for p > 0 comes strongly from the fact that, when only the interference pathway was simulated, statistically significant estimates for p > 0 were … WebDec 29, 2004 · Interference, by definition, means that crossovers somehow discourage other crossovers from occurring nearby. One simple model for how interference works is that a crossover generates some crossover-discouraging signal or substance that then spreads for some variable distance along the chromosome on either side of the crossover.
