Inbreeding and inbreeding depression
WebInbreeding depression is the decline in performance that is associated with inbreeding. Since inbreeding depression and heterosis from crossbreeding are essentially opposite effects, it is not surprising that the same traits that respond well to crossbreeding will respond adversely to inbreeding. These would include reproductive traits such as ...
