abstract：:Previous work on Drosophila santomea suggested that its absence of abdominal pigmentation, compared to the other darkly pigmented species, is based on mutations in the cis-regulatory region of tan, inactivating the expression of that gene in the abdomen of D. santomea males and females. Our discovery that D. santomea ...
