siren1 and siren2 are novel alcohol dehydrogenase (Adh)-derived chimeric genes in the Drosophila bipectinata complex. D. ananassae, however, harbors a single homolog of these genes. Like other Adh-derived chimeric genes, siren evolved adaptively shortly after it was formed. These changes likely shifted the catalytic activity of siren.
siren1和siren2是果蝇双栉果蝇复合体中新型的源自乙醇脱氢酶(Adh)的嵌合基因。然而,拟果蝇仅含有这些基因的一个同源物。与其他源自Adh的嵌合基因一样,siren在形成后不久就发生了适应性进化。这些变化可能改变了siren的催化活性。
