The chicken (G. domesticus) and turkey (M. gallopavo) were originally domesticated for religious reasons, and the water buffalo (Bubalus bubalis) primarily as a beast of burden (Zeuner, 1963). It is likely that the house cat (Felis silvestris catus) and the ferret (Mustela furo) were domesticated to protect stored grains and other food materials from rodents (Zeuner, 1963). Other species were domesticated as sources of food, clothing, labor, transportation, adornments or sacrificial offerings. In contrast, the domestic value of many wild species has been largely ignored or, if recognized, social and technological barriers have often prevented their domestication.
2000). , 1992). When mating is random, some families will inevitably be represented less than others or lost, resulting in increased inbreeding in the poorly represented families and reduced genetic variation. Severe inbreeding and inbreeding depression are less likely for the population as a whole with equal family representation in each generation. g. body conformation, trainability). Through systematic inbreeding, one can attain a degree of homogeneity and constancy of characteristics that is normally not seen in wild populations.
A case can be made for the wolf-like ancestors of the dog choosing humans in a kind of self-domestication, but it is doubtful that other species were likewise attracted to human settlements and domesticated in a similar manner. Chapter 5 Inbreeding Genetic adaptation to captivity probably occurs to some degree in all wild populations brought into captivity. The rate and extent of genetic change over time will differ with the species and the specific housing and management conditions employed (Bartlett, 1984; Frankham and Loebel, 1992).
