Designation of alleles follows the text. Numerals 1, 2, 3 and 4 correspond to Woods Hole, Wall, Willis Wharf, and Beaufort, respectively. 2), no variation within or between populations was evident. All individuals were identified as homozygotes for the same allele. Classification of urchins according to sex was dependent upon the development of the gonads. The gonads of all specimens from Willis Wharf were reduced, and the sexes could not be distinguished. Assignment of sexual status was possible for most urchins in the other populations. This data was used to calculate gene fre- quencies according to sex within each Atlantic coast population for each polymorphic locus. A Chi-square test for homogeneity of allele frequencies for the sexes indi- cated a lack of significant variation in intersex allele Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
