Abstract
1. 1. Repetitive DNA evolution has been studied in various reptilian species by means of the reassociation kinetics technique. 2. 2. Quantitative variations in genome sizes depend on differences essentially in repetitive DNA, but also in single-copy DNA. 3. 3. The behaviour of the variations in repetitive DNA in relation to the various taxonomic relationships existing among the species assayed, leads us to think that the duplicated fractions are mostly free to evolve. 4. 4. Some difference in repetitive DNA evolution is observed in Chelonia on one side and in Squamata on the other. © 1981.File in questo prodotto:
