Description The wild progenitor species of all cereals are known with various degrees of ceninty.
Wild and cultivated taxa of the same species cross and their hybrids are generally fertile. This
allows for a study of the genetics of domestication. A survey of the literature. however.
reveals few such studies. The adaptation to disturbed habitats is genetically complex. and
colonizing ability seems to have been a prerequisite for successful domestication. Natural seed
dispersal is controlled by one to several linked genes, and behaves genetically as an overall
dominant over loss of efficient seed dispersal mechanisms. Apical dominance, synchronized
tillering. and increase in fecundity are complex, recessive genetic traits associated with cereal
domestication. Racial evolution resulted from conscious selection by man and involves
numerous loci.
