Genetic analysis of developmental incompatibilities in hybrids. Hereditas. 1991;114(2):189-195. doi: 10.1111/j.1601-5223.1991.tb00323.x.http://hdl.handle.net/10400.13/3716The genetic analysis of two abnormal Characters, extra sex combs and abnormal head shape in hybrids between Drosophila madeirensis and Drosophila subobscura, revealed a major effect of the X chromosome in both cases. Autosomes also play a role in determining these abnormalities, the E chromosome in case of extra sex combs, the E and 0 chromosomes in case of abnormal head shape. Autosomes do not cause the two abnormal characters, without interacting with the X chromosome.engDrosophila madeirensisDrosophila subobscuraSpecies barrierGenetic analysisIncompatibilities in hybrids.Faculdade de Ciências da Vidajournal article10.1111/j.1601-5223.1991.tb00323.x
