Its breeding has followed millennia of cultivation, sometimes with unintended selection on adaptive traits, and later by applying intentional but empirical selective pressures. But additional experiments run by British evolutionary geneticist Robin Allaby and preliminarily reported in Watson (2018) have shown that ancient DNA from undersea sediments is more pristine than that from other contexts. Any observable changes in phenotype may have an underlying change in genotype, especially with sufficient time, since are linked in a cause & effect relationship. spelta) was widely cultivated in Europe until the 20 th century when it was largely replaced by bread wheat due to the agronomic superiority of the latter; however, spelt is still grown to a limited extent in Central Europe, particularly on marginal land, and may provide a Google Scholar, Doebley JF, Gaut BS, Smith BD (2006) The molecular genetics of crop domestication. Wheat domestication involves a limited number of chromosome regions, or domestication syndrome factors, though many relevant quantitative trait loci have been detected. The key domestication-related loci, originated over a wide geographical range, were gradually pyramided through a protracted process.
