Studies in Artificial Selection of Quantitative Characters I. Selection for Abdominal Bristles in Drosophila Melanogaster

Abstract

Genetic and phenotypic parameters for number of abdominal bristles were estimated from diallel crosses in a wild-type laboratory stock, Oregon-Reo Two replicate mass selection lines in both high and low directions were developed and run for over 30 generations. The same parameters were estimated from dianel ~rosses at intervals during the experiment.
