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). WebFeb 26, 2024 · Although inbreeding alone does not change allele frequencies, it does redistribute genetic variation, reducing it within families or populations while increasing it among families or populations.
