Fig. 3From: DNA polymorphism and selection at the bindin locus in three Strongylocentrotus sp. (Echinoidea)Sliding-window plots of polymorphism (Ï€, thin line) and divergence (K, thick line) along the bindin gene of S. intermedius (INT), S. pallidus (PAL), and S. droebachiensis (DRO). The bindin sequence of S. polyacanthus (AF077317) was used for the K calculations. Window sizes are 100 nucleotides with 1-nucleotide increments. A schematic representation of the bindin gene is at the bottom. Vertical arrows indicate the locations of the regions with high within species polymorphism and low between species divergenceBack to article page
