A tag SNP is a representative single-nucleotide polymorphism (SNP's) in a region of the genome with high linkage disequilibrium (the non-random association of alleles at two or more loci).
Although the caimans have much narrower bodies, they are most closely related to alligators and crocodiles. Caimans are found in a variety of habitats throughout Central and South America from marshes and swamps to mangrove rivers and lakes.he average length for most of the other caiman species if about 2.5 meters long. The caiman is a carnivorous predators and, like the alligator and the crocodile, the caiman has a diet that consists of a great deal of fish.
While alligators (and caimans) are often confused with crocodiles, they belong to two quite separate taxonomic families.The most obvious external differences are visible in the headâalligators and caimans have wider and shorter heads, and a more U-shaped than V-shaped snout.he alligator's upper jaw is wider than its lower jaw, and the teeth in the lower jaw fit into small depressions in the upper jaw.
