A recent study of inbreeding in United States Ayrshires suggests little inbreeding in that breed in spite of the relatively small population size. Inbreeding and preservation of genetic variation should be minor concerns in selecting sires. INTRODUCTION Inbreeding and selection were combined ef- fectively by pioneer animal breeders to establish ...Author summary Inbreeding depression is the reduction in fitness and vigor resulting from mating of close relatives observed in many plant and animal species. Mating of close relatives increases the probability that an individual inherits two non-functioning mutations at the same gene, resulting in lower fitness of such matings. We do not know the extent to which inbreeding depression is due ...Understanding and estimating inbreeding is essential for managing threatened and endangered wildlife populations. However, determination of inbreeding rates in natural populations is confounded by incomplete parentage information.
