mixed population experiment. Drosophila melanogaster

Mixed populations of Oregon-R-S from the Bloomington Stock Center (BL#4269) and Dark-fly (D1388-3) were reared in light/dark cycling (LD) or constant dark condition (DD). Genomic DNA was extracted from the mixed population at generation 0, 22nd and 49th (1 replica from generation 0, 3 replicas each in LD and DD from generation 22nd and 49th, 13 populations in total). Generation 0 was hybrid of Oregon-R-S and Dark-fly.
