Amplification success of conserved microsatellite loci in three species of Charadriiformes (Kentish plover, whiskered auklet and ruff) in relation to the E-value of the chicken- Charadriiformes hit. Loci with both flanks matching the chicken sequence at the same chromosomal region of the chicken are considered. Smaller E-values indicate higher probability of identity. Open circles each represent a single microsatellite locus. The line represents predicted values derived from the statistical model (see text).
