Is domestication a single-gene trait?
Domestication is typically defined as a process whereby a group of animals become dependent upon humans for the continuance of their genetic kind. Additionally, domestication is traditionally viewed as having progressed through stages starting with the taming of a few animals and continuing as the traits gradually change genetically as the animals become “more domesticated.” However, some research within recent years has implied that domestication may be a rapid genetic change involving a complex of genes that are possibly under the control of a “master gene”. This complex of genes affects many facets of behavior and morphology in the domesticated species including: tameness, reaction to stress, coat color, facial morphology, and social interactions. A correct understanding of the genetic basis of domestication should enhance the ability of humans to efficiently and appropriately use and maintain domesticated animals.
