TLDR
Using a combination of molecular and FISH analyses, it is proved that male specific Restriction site-Associated DNA sequences (RADseq) isolated in C. calyptratus are conserved in C.'s chamaeleon and located the putative XY chromosomes on the second chromosome pair.About:

TL;DR: The presence of ITRs is generally rare in turtles, which agrees with the expected low rates of chromosomal rearrangements and rather slow karyotype evolution in this group, and support that centromeres and non-recombining parts of sex chromosomes are very dynamic genomic regions, even in turtles.

Lizards as Model Organisms of Sex Chromosome Evolution: What We Really Know from a Systematic Distribution of Available Data?
TL;DR: In this paper, the authors present a synthesis of general genome and karyotype features of non-snakes squamates and discuss the main theories and evidences on the evolution and diversification of their different sex determination and sex chromosome systems.

TL;DR: This work assembled a chromosome-level genome for a gecko and used this assembly to search for sex chromosomes among six closely related species using a variety of genomic data, including whole-genome re-sequencing, RADseq, and RNAseq, which confirmed two different linkage groups as XY sex chromosome systems that were previously unknown to act as sex chromosomes in tetrapods.

Sex Chromosomes and Master Sex-Determining Genes in Turtles and Other Reptiles
TL;DR: A review of the current knowledge of reptilian sex chromosomes at the cytogenetic and molecular level can be found in this paper, where a few putative master sex-determining (MSD) genes have been proposed, but none has been demonstrated yet.

A phylogeny and revised classification of Squamata, including 4161 species of lizards and snakes
TL;DR: A new large-scale phylogeny of squamate reptiles is presented that includes new, resurrected, and modified subfamilies within gymnophthalmid and scincid lizards, and boid, colubrid, and lamprophiid snakes.
