What is Low mitochondrial DNA variation among American alligators and a novel non‐coding region in crocodilians about?
## Abstract We analyzed 1317–1823 base pairs (bp) of mitochondrial DNA sequence beginning in the 5' end of cytochrome __b__ (cyt b) and ending in the central domain of the control region for 25 American alligators (__Alligator mississippiensis__) and compared these to a homologous sequence from a Chinese alligator (__A. sinensis__). Both species share a non‐coding spacer between cyt b and tRNA^Thr^. Chinese alligator cyt b differs from that of the American alligator by 17.5% at the nucleotide level and 13.8% for inferred amino acids, which is consistent with their presumed ancient divergence. Only two cyt b haplotypes were detected among the 25 American alligators (693–1199 bp surveyed), with one haplotype shared among 24 individuals. One alligator from Mississippi differed from all other alligators by a single silent substitution. The control region contained only slightly more variation among the 25 American alligators, with two variable positions (624 bp surveyed), yielding three haplotypes with 22, two, and one individuals in each of these groups. Previous genetic studies examining allozymes and the proportion of variable microsatellite DNA loci also found low levels of genetic
