However, this observation remains today largely unexplained despite several attempts. Based on very limited observations (see Table 1), especially of Bombyx, in which the female is heterogametic, Haldane [3] suggested, as far as “these facts are anything more than a coincidence,” that the lower autosomal recombination rate in the heterogametic sex may reflect a pleiotropic consequence of selection against recombination between the sex chromosomes. Later, Huxley [4] showed that Gammarus males also recombined less than females. He gave the same evolutionary explanation, although he restricted it to cases of a marked sex difference.","tracks":[]}
