So it leads us to know that our genetic load is potentially quite large for the population, and if we're focusing on just one set of genes or a particular gene, we may be not understanding our whole scope of what our genome component and our whole genetic load might be on the population.
When genetic load is determined primarily by recessive mutations, interactions between the mating system and inbreeding depression should lead to one of two evolutionary stable endpoints: predominant outcrossing associated with strong inbreeding depression or predominant self-fertilization with weak inbreeding depression (Lloyd 1979; Lande and Schemske 1985; D.
