    • ‘Fully recessive mutations are maintained in higher frequencies than partially recessive ones and thus cause greater declines in fitness under consanguineous matings.’
    • ‘The most obvious is the mating system, which generates ‘short-term’ inbreeding, i.e., inbreeding caused by one or a few generations of consanguineous matings.’
