The genus Phaseolus , native to the Americas, is composed of more than eighty wild species, five which were domesticated in pre-Columbian times. Since beginning domestication events this genus, ample opportunities for gene flow with relatives have existed. present work reviews extent primary and secondary areas aim illustrating how evolutionary force may conditioned ecological fitness widesprea...

Geographical isolation facilitates the emergence of distinct phenotypes within a single species, but reproductive barriers or selection are needed to maintain polymorphism after secondary contact. Here, we explore processes that intraspecific variation C4 photosynthesis, complex trait results from combined action multiple genes. The grass Alloteropsis semialata includes and non-C4 populations, ...
