  1. Breed reptiles in captivity: Crocodilians

    A review of studies investigating the genetics of captive breeding programmes (Witzenberger & Hochkirch 2011) found that captive breeding reptiles had mixed genetic outcomes in comparison to wild populations. Nine percent of 131 studies related to reptiles. One study on American alligators Alligator mississippiensis found that captive breeding had a positive effect on two measures of genetic diversity (measured as expected heterozygosity and number of alleles), but a negative effect on the chance of inbreeding compared to wild populations.  Two databases (Web of Science and Zoological Record) were searched for studies investigated the genetics of captive populations up until 2010.
