A herança e o desequilíbrio de ligação entre 11 locos polimórficos de oito sistemas isoenzimáticos foram estudados em progênies de polinização aberta de duas populações de Eschweilera ovata (Bambess.) Miers (biriba) do Estado da Bahia. A análise da segregação de progênies de árvores heterozigotas revelou simples herança mendeliana para onze locos (Acp-1, Dia-1, Dia-2, Dia-3, G6pdh-1, Mdh-1, Nadh-1, Nadh-2, Pgi-1, Pgi-2 e 6pgdh-1). A segregação desses locos foi geralmente homogênea entre árvores, embora algumas tenham apresentado desvios significativos da segregação esperada 1:1. Desvios significativos do equilíbrio gamético foram detectados entre três pares de
