Hybrid animals often have lower fitness than individuals of their parent species (Harrison 1993 and references therein) as a result of incompatible genetic combinations, such as Dobzhansky-Muller incompatibilities (Dobzhansky 1937, Muller 1942, Bolnick and Near 2005), mismatched chromosomes (Shaw and Wilkinson 1980, Searle 1993), incompatible cellular organelles (e.g.

Como afirma Formiga (2010, p.12), o centro da escola era o Departamento de Biologia Geral, dirigido pelo professor AndreDreyfus, que era medico e professor de histologia, dava aulas de laboratorio e preparava material didatico sobre as teorias da evolucao e genetica na Faculdade de Medicina de Sao Paulo.A partir de 1943, o Departamento de Biologia mudaria o rumo das pesquisas, incorporandose a um projeto liderado por Theodosius Dobzhansky que envolvia o inicio de estudos na sistematica e morfologia de Drosophila e genetica de populacoes.

Aunque algunos autores de la nueva sintesis rechazan la premisa de una variacion ilimitada e isotropica (por ejemplo, Dobzhansky, 1974; Endler, 1986; Williams, 1992), esta perspectiva no es la norma.
