Partial Inbreeding: Equilibrium Heterozygosity and the Heterozygosity Paradox

The effect of partial inbreeding on equilibrium populations has been extended to any degree of mating. As expected, for distantly related mates, the equilibrium levels of inbreeding and heterozygosity are not affected as much as by partial selfing. Formulas are also given for equilibrium levels of i...

Description
Summary:The effect of partial inbreeding on equilibrium populations has been extended to any degree of mating. As expected, for distantly related mates, the equilibrium levels of inbreeding and heterozygosity are not affected as much as by partial selfing. Formulas are also given for equilibrium levels of inbreeding and heterozygosity when two or more degrees of mating are present in a population. Inbreeding, other than selfing, may partially explain the deficiency of heterozygotes in outcrossers, part of the "heterozygosity paradox."
