Fruitflies and nematodes show many similarities in the general organization of the gene networks that control sexual dimorphism and dosage compensation. In contrast, the underlying molecular mechanisms appear to be very different in these two species. Developmental processes such as sex determination need not be strongly conserved in evolution.
果蝇和线虫在控制性别二态性和剂量补偿的基因网络的总体组织方面表现出许多相似之处。相比之下，这两个物种的潜在分子机制似乎非常不同。性别决定等发育过程在进化中不一定会被强烈保守。
