Summary
An electrophoretic investigation of 22 gene loci in a local sample of a widespread and ecologically extremely versatile gecko species has shown a low degree of heterozygosity, as is average in lizards and other vertebrates.

The geckos were collected around a building by Jean-Louis Pasteur, whom we are glad to thank.

The Nevo review1 does not give the criteria used for polymorphism estimates, and since it mixes estimates made with 0.01, 0.95 and 0.05 criteria and even estimates not based on random samples of loci, it can hardly be relied on for comparisons. Unfortunately, only the earliest3 of the 3 comprehensive reviews of animal genic variation1–3 gives both local and total polymorphism estimates together with their criteria.
