P element transposon-induced quantitative genetic variation for inebriation time in Drosophila melanogaster.
Bi-directional selection was carried out in coisogenic stocks with and without mobilised P element transposons to determine whether P elements induce quantitative genetic variation for inebriation time in Drosophila. There was significant response to 11 generations of selection in both pairs of replicates of bi-directional selection from an isogenic base stock in which P elements had been mobilised. Conversely, there was no significant response to 11 generations of identical selection in the control lines derived from a relatively inbred line lacking P elements. Thus, P elements have induced quantitative genetic variation for inebriation time.
