Types when you look at the genotypic team, like animals and wild wild wild birds, have sex chromosomes, which in reptiles are available in two major kinds. Numerous species—such as a few types of turtle and lizards, such as the iguana—have that is green and Y intercourse chromosomes (again, like animals), with females being “homogametic,” this is certainly, having two identical X chromosomes.
