  • a Data taken from Rothenfluh et al. (2000b).

  • Flies were entrained to 12 hr:12 hr LD cycles for 5 days and then released into DD, where their behavior was monitored for an additional 5–7 days. Except for the EP(X)sgg and sggD127/FM7 flies, all other variants were in a y w genetic background. Period values (τ) were determined by a χ2 periodogram; only flies showing periods in combination with a “power” value ≥10 and a time bin “width” ≥2 were considered rhythmic (materials and methods).
