Types within the genotypic team, like animals and wild birds, have intercourse chromosomes, which in reptiles may be found in two major kinds. Numerous species—such as a few types of turtle and lizards, just like 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.
