Correlation Between Bristle Systems in Drosophila Melanogaster

Abstract

The correlation between several bristle systems of Drosophila melanogaster was investigated. The changes in sternopleural, second coxal, third coxal, and scutellar bristle numbers were measured in 26 lines selected for increased abdominal bristle number for 46 or 50 generations. The changes in abdominal, second coxal, and scutellar bristle numbers were measured in 16 lines selected with independent culling levels for high or low sternopleural and high or low third coxal bristle numbers for 22 generations.
