Number and length of XY1 sequence copies found. Indicated are also which parts of the region that are covered in which taxa. The "n" row indicates number of PCR fragments included in the probabilistic calculations of sequence numbers. The "p" row indicates the posterior probabilities that we did find all sequence copies (see Methods for formula). The divergence estimates are means from pairwise Tamura-Nei distances ± standard error (SE) from sequences within an individual, and mean distances to sequences from other individuals.
