Second, of the half of the clutch exhibiting distinct pigmentation, approximately half were strongly pigmented (upper two rows Table III) while the remaining half (rows 3 and 4) exhibited a similar color, but of much weaker intensity, presumably because half were homozygous recessive and half heterozygous at the pigment intensity locus (OI; until the dominance relationship is established at this locus, genotypes cannot be assigned). It is also possible that the presence of the mottled, pale yellow pigmentation in some of the 'unpigmented' individuals (rows 5 and 6, Table III) resulted from one of the alleles at this proposed pigment intensity locus. Third, all those offspring ex- hibiting distinct pigmentation showed some evidence of banding (upper four rows); TABLE V Results of contingencv table analvses of banding frequency variation in Thais emarginata (data in Table IV)1 Comparison df Sig Between microhabitats.
