Their importance is also suggested by theoretical work on Haldane's rule, which states that the viability or fertility of the heterogametic sex is more likely than that of the homogametic sex to be reduced in hybrids (Haldane 1922).
This may be due to the sex in papaya which is determined by a single gene with three alleles, in which males and hermaphrodites are heterogametic, while females are homogametic [24, 25].
Normally, the heterogametic sex (males in XY/XX systems, females in ZW/ZZ systems) shows lower chiasma frequencies than the homogametic one (Trivers 1988, Burt et al.
When both loci are autosomal, or when all sampled individuals are of the homogametic sex, then this method reduces to the form given in Hill (1974).
Although Haldane's rule applies to asymmetrical sterility or viability between homogametic and heterogametic hybrids in most diploid species, it is not directly relevant to species with other sex determination systems simply because they lack sex chromosomes and a heterogametic sex.
Haldane (1922) observed that when hybridization occurs between different animal races, the heterogametic sex more often suffers reduced survivorship or fertility than the homogametic sex.
