On Crossing Between <i>Drosophila bipectinata</i> and <i>Drosophila malerkotliana</i>

Abstract

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.
