The assumption that these phenotypes were under the control of 5 allelic genes was supported by the observed distribution of the phenotypes. There were no significant differences in PGM phenotyope distribution between sexes or among samples of shrimp collected from Matagorda and Galveston Bay, Louisiana; and the north Edisto River, South Carolina. The 5 PGM alleles observed in white and brown shrimp appear to be the same in the 2 spp. Comparisons of PGM phenotype distributions and allele frequencies of white and brown shrimp suggest that the 2 spp are closely relatedallelesAplocheilus latipesCulturesDistributionelectrophoresisEnvironmental effectsfeedingGalveston BaygenesLaboratoriesLightQ1 01182 Methods and instrumentsTemperatureJournal
