How does inbreeding alter genotype and allele frequencies?
erik [133]

Explanation:

The inbreeding process, are blood crossings between relatives who have a common ancestor. Inbreeding leads to an increase in the frequency of homozygous genotypes and a decrease in the frequency of heterozygotes. We may also note that although changes in genotypic frequencies occur, no changes in allelic frequencies are observed over successive generations of self-fertilization. The main consequence of 2 individuals sharing one or more common ancestors is that they may carry replicas (identical copies) of one or more genes present in these ancestors. And if these individuals mate, they can pass on such replicas to their offspring, generating self-sibling offspring, that is, with two identical copies of the same gene that was present in these common ancestors.
