Gene Flow Between Crops and Their Wild Progenitors

  title={Gene Flow Between Crops and Their Wild Progenitors},
  author={Roberto Papa},
Gene flow occurs when there is migration of individuals (e.g., seeds) or gametes (e.g., pollen) between populations. Along with drift, selection, and mutation, it represents one of the main evolutionary forces causing changes in gene frequencies. The main effect of gene flow is the reduction of differentiation between populations accompanied by a parallel… CONTINUE READING
