Effectiveness of Regular Cycles of Intermittent Artificial Selection for A Quantitative Character in Drosophila Melanogaster

Abstract

Regular cycles of intermittent mass selection have been compared with continuous mass selection at the same selection intensity for the quantitative trait of bristle number on one abdominal segment in a non-inbred strain of Drosophila melanogaster. All lines had 20 pairs of parents per generation. There were four replicates of each intermittent selection treatment, six of continuous selection at 20% selection intensity, and two at 10% selection intensity.
