The data provide size distribution of male (size1) and female (size2) in Littorina saxatilis mating pairs from 32 samples (pop). The samples are classified in two groups (area), those representing bimodal populations with tw ecotypes living in sympatry and able to meet for mating (area 1) and those living in unimodal populations with only one ecotype present. For every mating pair the ecotype type of each sex, mor1 (for male) and mor2 (for female) is also provided (1 shelter, 2 intermediate and 3 exposed ecotypes).
