WebApr 14, 2024 · Pedigrees have historically been used to estimate the coefficient of inbreeding. Pedigree COI is based on predicted DNA inheritance, such as a dog sharing on average 50% of DNA from each parent.

When two closely related organisms mate, their offspring have a higher level of homozygosity: in other words, an increased chance that the offspring will receive identical alleles from their mother and father. In contrast, heterozygosity occurs when the offspring receives different alleles. Dominant traitsare … See more The risk of a child developing an autosomal recessive disorder increases with inbreeding.

WebMay 4, 2024 · Inbreeding tends to increase the proportion of homozygous loci, some of which cause homozygosity of recessive alleles that results in reduced performance. This phenomenon is known as inbreeding depression and tends to be most prominent on fitness-related traits, such as male fertility.
