THE DISTRIBUTION AMONG POPULATIONS IN PHENOTYPIC VARIANCE WITH INBREEDING.

摘要: The effects of inbreeding on the phenotypic variance within populations were measured in a set 30 bottlenecked lines derived from single source population Drosophila melanogaster. Inbred had significant among amount lines, for thorax length, and sternopleural bristle scores. When significance levels corrected an experimentwide basis, no line increases counts, although two length variance. These results demonstrate that inbred cannot be treated as necessarily more uniform than outbred changes due to should with caution unless there has been sufficient replication. also validity important assumption models evolution by variance-mediated mechanisms, such variance-induced peak-shift model.
