CROSSOVER ZONES. “Many sex chromosome pairs have suppressed recombination extending over much of the Y, except for a small ‘pseudoautosomal’ region or regions (PAR) to which pairing and recombination are restricted. Since one crossover per chromosome arm is often required for disjunction, crossover rates are likely to be extremely high in these regions.”
