No diagram. The mother had the genes for eosin, ruby, and forked in one X chromosome, and the genes for fused in the other. The father was bar. The eyes of the gynandromorph were bar (homozygous or heterozygous?); the wings were abnormal; the abdomen was female, with female genitaha somewhat abnormal. DROSOPHILA GYNANDROMORPHS PREVIOUSLY PUBLISHED. There are several references to cases where white spots were found in the eyes of Drosophila, sometimes in cases where the gene for white eyes might have been present (Amer. Naturahst, xlvxii, Aug. 1913, p. 509; Morgan, Science, xxxiii, Apr. 1911, p. 534). No. I. J. S. Dexter, 1912. Biol. Bull. August 1912. Parentage.—The mother carried the gene for yellow and white in one X and only wild-type genes in the other. Description.—Although the individual is described as a female, it is more likely that the yellow white right side was male and the wild-type left side female. This female was found to be sterile, which agrees better with the assumption that the right side was male, since mosaics which are entirely or even more than half female usually are fertile. Explanations.—A yellow white X egg was fertilized by a wild-type X sperm.
