Reptile genome sequenced

摘要

The first non-avian reptile genome has been sequenced - that of the North American green anole lizard (Anolis carolinensis). The anole is an emerging model for the study of adaptive radiation and convergent evolution. The genome includes a previously unknown X chromosome, with no homology to known amniote sex chromosomes, and microchromosomes that share common ancestry with those in birds, but without their unusual characteristics.
