Squamata is the largest reptilian order including snakes and lizards which occupies a key position in phylogeny of amniotes. A variety of sex determination modes in lizards is one of the most interesting parts of the biology of this order. These mechanisms are genomic sex determination (both XY and ZW systems) and temperature-dependent sex determination. Studies of squamata sex chromosomes are pivotal for understanding evolution of other vertebrate sex chromosomes. Unfortunately, this clade has long been neglected by molecular geneticists. In this paper, we describe recent data on molecular cytogenetics and genomics of squamates, evolution of their sex chromosomes and sex determination mechanisms.
有鳞目是最大的爬行动物目，包括蛇和蜥蜴，在羊膜动物系统发育中占据关键位置。蜥蜴的多种性别决定模式是该目生物学中最有趣的部分之一。这些机制包括基因组性别决定（XY和ZW系统）以及温度依赖型性别决定。对有鳞目性染色体的研究对于理解其他脊椎动物性染色体的进化至关重要。不幸的是，这个进化枝长期以来一直被分子遗传学家忽视。在本文中，我们描述了关于有鳞目分子细胞遗传学和基因组学、其性染色体进化以及性别决定机制的最新数据。
