Randomized trial assesses genetic influences on sleep rebound in Drosophila, indicating potential for genetic mapping.

This research aims to understand the genetic basis of varying responses to sleep deprivation in Drosophila melanogaster.
Analyzed sleep and activity in over 100 Drosophila lines from the Drosophila Genetic Reference Panel 3 (DGRP3).
Implemented a protocol involving 12 hours of mechanical sleep deprivation followed by recovery sleep measurement.
Controlled experiments with the Canton-S B strain and conducted three independent replicates for each genotype.
All genotypes experienced sleep loss, with 7% exhibiting no sleep rebound.
Heritability estimates for total sleep ranged from 0.39 to 0.50, indicating significant genetic influence.
Genotype and sex were significant factors affecting behavioral responses to sleep deprivation.

Colt et al. (2026) studied this question.
