Fig. 1.—. Genotypic scenarios for sex-linked regions. Expectations for heterozygosity depend on which sex is heterogametic and the region of the sex chromosome (pseudoautosomal region vs. sex-determining region). Female heterogamy is potentially associated with female-biased heterozygosity (Scenario 1a), male-only heterozygosity (Scenario 2a), or female-only homozygosity with no male genotypes (Scenario 3c). Corresponding scenarios (Scenarios 1b, 2b, and 3b) apply to the opposite sex for male heterogamy.
