GENETICS OF NATURAL POPULATIONS. XXII. A COMPARISON OF THE CONCEALED VARIABILITY IN DROSOPHILA PROSALTANS WITH THAT IN OTHER SPECIES

Abstract

ROSOPHILA PROSALTANS occupies a rather unique position D among the species of Drosophila which have served as materials for studies on genetic population structure. For obvious technical reasons, these materials are usually chosen amongst species that are common, widespread. and occur in a variety of habitats. D. melanogaster is one of the best laboratory animals, and is also an "animal weed" which has reached a near-cosmopolitan distribution as a commensal in human household,s. D.
