WebFeb 26, 2015 · Inbreeding refers to the mating among related individuals and results in an increase in homozygosity. The fitness costs associated with inbreeding are due to recessive deleterious alleles that confer a disadvantage on the individual possessing them. WebDec 5, 2024 · Inbreeding can alter the gene pool. This is because it predisposes to homozygosity. Potentially harmful recessive alleles — invisible in the parents — become exposed to the forces of natural selection in the children. Figure 18.6.1: Assortative mating.

WebOne effect of inbreeding is to increase the frequency of homozygotes (and thus, necessarily, decrease the frequency of heterozygotes). Note: while the frequency of genotypes change with inbreeding, the frequencies of alleles remains the same (assuming no selection, migration, mutation).

WebWhat does heterozygosity tell us, and what patterns emerge as we go to multi-allelic systems? Let’s take an example. Say p = q = 0.5. The heterozygosity for a two-allele system is described by a concave down parabola that starts at zero (when p = 0) goes to a maximum at p = 0.5 and goes back to zero when p = 1. In fact, for any multi-allelic ...
