Zona híbrida

Uma zona híbrida existe onde a distribuição de duas espécies não isoladas reprodutivamente se encontram. Para uma zona híbrida ser estável, os descendentes produzidos pelo cruzamento das espécies (os [híbrido (biologia)|híbridos) têm de ser menos aptos que os membros das espécies parentais, embora esta condição não seja necessária na primeira geração (Híbrido F1) que pode apresentar vigor híbrido. Algumas zonas híbridas movimentam-se.
