Conservationists use breeding programs to try to help the recovery of endangered species by preserving the existing gene pool and preventing inbreeding. There also can be breeding programs for plants.
Closely monitoring the possibility of inbreeding within the captive bred population is also key to the success of reintroduction into the species' native habitat. The Speke's Gazelle was the focus of a captive breeding program centered on determining the effect of selection on reducing genetic load.
Inbreeding is the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically. [1] By analogy, ...
This technique can be used to identify the genomic footprint of inbreeding in conservation programs, as organisms that have undergone recent inbreeding will exhibit long runs of homozygosity. For example, the step-wise reintroduction strategy of the Alpine Ibex in the Swiss Alps created several strong population bottlenecks that reduced the ...
It included coerced sexual relations between enslaved men and women or girls, forced pregnancies of enslaved women and girls due to forced inter inbreeding with fellow slaves in hopes of producing relatively stronger future slaves. [1]
By "breeding the best to the best", employing a certain degree of inbreeding, considerable culling, and selection for "superior" qualities, one could develop a bloodline or "breed" superior in certain respects to the original base stock. Such animals can be recorded with a breed registry, the organisation that maintains pedigrees and/or stud books.
A study carried out by Culloty et al. showed that 'Rossmore' oysters in Cork harbour, Ireland had better resistance compared to other Irish strains. A selective breeding program at Cork harbour uses broodstock from 3– to 4-year-old survivors and is further controlled until a viable percentage reaches market size. [43] [44]
Therefore the coefficient of inbreeding of individual G is = (+) = + = %. If the parents of an individual are not inbred themselves, the coefficient of inbreeding of the individual is one-half the coefficient of relationship between the parents. This can be verified in the previous example, as 12.5% is one-half of 25%, the coefficient of ...
