On Crossing Between Drosophila bipectinata and Drosophila malerkotliana

抄録

Drosophila malerkotliana differs from Drosophila bipectinata in the presence of seven paracentric inversions, three on the second and four on third chromosomes. The three inversion complexes have been analysed on the basis of the reference map of the salivary gland chromosomes of D. malerkotliana. The probable course of events in the evolution from the common ancestral population, have been discussed. The F₁ hybrids are sterile when crossed among themselves.
