Haldane's rule applies to the vast majority of heterogametic organisms examined, including when two species, where secondary contact in an area of sympatry results in incomplete reproductive isolation, form hybrids after allopatric speciation has occurred.
This includes the case where two species make secondary contact in an area of sympatry and form hybrids after allopatric speciation has occurred. Haldane's rule applies to the vast majority of heterogametic organisms.
