Introduction. The term "inbreeding depression" encompasses a reduction of a trait, often associated with lifetime fitness, as a sequela to a sustained rate of breeding of closely related individuals (reviewed in Charlesworth and Willis 2009; Hedrick and Garcia-Dorado 2016).While inbreeding depression has been extensively explored in plants (Lande and Schemske 1985), geographically isolated ...To reduce the risks of inbreeding depression and genetic disorders, particularly for highly inbred breeds, such as Abyssinian cats, as well as Russian Blue …The consequence of reduced cognitive ability from inbreeding has long been investigated, mainly restricted to cousin-cousin marriages.
