National Park Service Biologists have recently reported the first abnormalities in mountain lions- a kinked tall where the end is shaped like the ' L and only one descended toenirie The renort indicated that these abnormalites are cased by low genetic diversity, What mechanisms below could explain the detrimental effects of low genetic diversity in small populations? Diversifving selection and disassortative mating Disassortative mating and inbreeding depression Directiona selection and mutation Genetic ditt and inbreeding depression Genetic diit and disruptive selection.
