Abstract

Developmental similarities between two eye abnormalities of Drosophila melanogaster, which had been detected in different laboratories, were indicated when the written description of each were compared. For experimental comparison, an exchange was made between the stock carrying the temperature-sensitive eye mutant "scarp", discovered by Hansen and Gardner (1962) at Utah State University, and the mutant “witty”, discovered by Whitten (1964) at the University of Tasmania. Scarp is expressed as a horizontal depression and a reduction in the ventral one-third of the compound eye when flies carrying the gene (scrp) in homozygous condition are reared at temperatures above 25 C. Witty is somewhat like scarp in phenotype and was found to be expressed at temperatures above 25 C. Similarities in phenotype as well as response to temperature suggested the possibility of common developmental processes. Comparisons between the two eye mutants, witty and scarp, are reported in this paper.
