GENETICS OF SEXUAL ISOLATION BETWEEN <i>DROSOPHILA PSEUDOOBSCURA</i> AND <i>DROSOPHILA PERSIMILIS</i>

Abstract

The following mutant strains of D. pseudoobscura were used: (I) yellow, singed, vermilion, compressed, short (y, sn, v, CO, sh), ( 2 ) orange (or), (3) orange purple (or pr), (4) white ( w ) , (5) aristapedia (ast), and (6) Bare Curly (Ba Cy). Mutants affecting different parts of the body are included in this list: a body color mutant yellow; eye color mutants vermilion, orange, purple, and white; bristle mutants singed and Bare; wing mutants short and Curly; and an antenna mutant aristapedia. With the exception of Bare and Curly, which are dominant and lethal when homozygous, all other mutants are recessive and viable in homozygous condition. The wild type flies used were obtained from a Piiion Flats (California) strain.
