Vavilovian Mimicry

Vavilovian mimicry (also known as crop mimicry or weed mimicry) is a form of plant mimicry in which weeds, through generations of artificial selection, acquire one or more traits that resemble those of a cultivated crop. This mimicry was discovered and named by the prominent Russian plant geneticist Nikolai Ivanovich Vavilov (founder of the theory of centers of origin of cultivated plants). Selection against weeds can occur during both the seedling and mature stages, and can also involve separating their seeds from crop seeds through winnowing, or both.
