- Title
Reptile Evolution and Genetics: An Overview.

- Abstract
In this species, several chromosome races differ in the number and morphology of chromosomes due to centric fission and pericentric inversions on various pairs of chromosomes. Despite the ancient divergence time, all crown reptiles' chromosomes and genome variability are low. As no intact DNA is available from fossil dinosaurs, information about extinct dinosaurs' karyotypes can be inferred via comparative analysis of chromosomes and genomes of several species of birds and non-avian reptiles. Analysis using FISH and BLAST methods shows that one DNA is mainly localized at the centromere of species belonging to both families, whereas the others form clusters specific on specific chromosomes or subsets of chromosomes.
