DEFINITION

Principio que establece que cuando una muestra pequeña de una población mayor se establece como entidad aislada nueva, su acervo genético lleva sólo una parte de la diversidad genética representada en la población de origen. De tal manera, resulta probable que los destinos genéticos de la población de origen y de la nueva población se establezcan de maneras diferentes, ya que las presiones evolutivas de las diferentes áreas de las dos poblaciones operarán sobre distintos acervos genéticos.
The principle that when a small sample of a larger population establishes itself as a newly isolated entity, its gene pool carries only a fraction of the genetic diversity represented in the parental population. The evolutionary fates of the parental and derived populations are thus likely to be set along different pathways because the different evolutionary pressures in the different areas occupied by the two populations will operate on different gene pools.
