Abstract
Y and W chromosomes start degenerating after they evolve a non-recombining region that is always heterozygous in males (Y) or females (W), sometimes losing almost all genes that were originally present on their X or Z counterparts. A new model for such degeneration involves evolutionary change in regulatory sequences.
摘要
Y 和 W 染色体在进化出一个在雄性（Y）或雌性（W）中总是杂合的非重组区域后开始退化，有时会失去几乎所有最初存在于其 X 或 Z 同源染色体上的基因。这种退化的一个新模型涉及调控序列的进化变化。
