Sequences for a phylogenetic analysis usually come from two sources: electronic databases and your own experimental results. Ideally, all of the sequence data needed can be obtained from databases, or at least all of the data needed except that of the specific organism(s) of interest. However, you might find that some other sequences you need for comparison are unavailable; if this is the case, you may need to obtain them yourself experimentally.
