    How do species go extinct by inbreeding if MR works?

    Some species are outcompeted simply, but some dwindle (cheetahs are so
    genetically homogenous due to population size reduction over the years
    that skin grafts between unrelated animals more or less always take, for
    example) and as they dwindle, genetic drift moves them away from the
    optimal configuration for the species (fixation of deleterious alleles).

    Genetic drift explains this perfectly, with no bits left over. How about
    MR? And why does the MR 'go wrong' for them in the first place (again
    the geneticist's explanation holds up with no visible strain here).
