The genome of this diploid species is usually designated AmAm to distinguish it from the lineage that led to hexaploid wheat. Part of wheats adaptability is due to the fact that it occurs both as winter habit varieties (requiring a cold period of 6 to 8 weeks to trigger reproduction), and spring habit varieties (not requiring the cold period). Domestication has genetically not only transformed the brittle rachis, tenacious glume and non-free threshability, but also modified yield and yield components in wheat. 2021 Jun 2;2(2):156-169. doi: 10.1007/s42994-021-00039-0. 2008.

Therefore, the synthetic lines are typically crossed to an adapted wheat cultivar, then backcrossed once or twice to the adapted cultivar, followed by selection. This change was possible because of a random mutation in the wild populations at the beginning of wheat's cultivation.

Turk J Agric Forest 27:5969, CAS Its domestication coincides with the beginning of agriculture and since then, it has been constantly under selection by humans. But other experiments led by evolutionary geneticist Robin Allaby and originally published in Watson (2018) suggest that ancient DNA from submarine sediments is less degraded than in other environments.
