In most sexually reproducing organisms, the heterogametic sex has fewer recombination events and a shorter recombination map than does the homogametic sex. Data adapted from J. L. Weber et al. (1993)In most sexually reproducing organisms, the heterogametic sex has fewer recombination events and a shorter recombination map than does the homogametic sex. Data adapted from J. L. Weber et al.
