What is a PopSet? A PopSet is a set of DNA sequences that have been collected to analyse the evolutionary relatedness of a population. The population could originate from different members of the same species, or from organisms from different species. They are submitted to GenBank via Sequin, often as a sequence alignment.

Example of a PopSet The snapping shrimp (genus Alpheus) earns its name from the noise made by the rapid shutting of its snapping claw — used to stun or kill prey. Alpheus is a particularly diverse genus, making it ideal to estimate rates of evolution. Sequence data from two nuclear genes and one mitochondrial gene suggest that Alpheus encompasses three major clades, consistent with previous morphological data, and that specialized ecological requirements and different claw morphologies have evolved independently several times.
