WebAug 1, 2024 · Inbreeding depression can also be generated by epistasis between dominance effects across loci, such that favorable gene combinations among heterozygous genotypes decrease in frequency during the inbreeding process (Jain and Allard, 1966). Under the first 2 hypotheses, in the absence of epistasis inbreeding depression is a linear function of ...
