On selecting for pupation height inDrosophila simulans
- 10 Downloads
Selection for high and low pupation height has been carried out in a baseD. simulans population derived from recently collected isofemale lines. Only the selection for increased pupation height was successful. At generation 8 around 50% of the individuals in the high lines attained the upper end permitted by the apparatus, and selection was stopped. The mean realized heritability was 18%. The finding of additive genetic variation for pupation height inD. simulans settles the question posed by a previous failure of selection reported in this species.
