WebApr 14, 2024 · Inbreeding is the production of offspring from the mating of genetically related individuals. 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. WebMar 10, 2024 · Inbreeding is a mode of breeding between individuals or organisms that are closely related. A consanguineous relationship has some serious disadvantages. For instance, it increases the tendency of producing offspring with genetic anomalies and congenital birth defects. Inbreeding increases the chances of acquiring deleterious traits.
