Exploration behavior

Drosophila Synthetic Population Resource

1,2

Bulk-segregant analysis population

“Exploring” flies are those found in the B chamber after 6 hours. “Non-exploring” flies are those found in the A chamber after 6 hours.

Allelic frequency differences

Simulated allelic frequency differences between flies that exhibit exploration behavior and flies that don’t.
