Abstract The author developed and tested a protocol for determining the sex of individual pinnipeds using the sex-chromosome specific genes ZFX and ZFY. The author screened a total of 668 seals of known or unknown sex and compared the molecular sex to the sex assigned at the time of collection in the Ross and Amundsen Seas, Antarctica. Discrepancies ranged from o% to 6.7% among species. It is unclear, however, if misassignment of sex occurred in situ or in the laboratory. It also is possible, however, that the assigned morphological and molecular sex both are correct, owing perhaps to developmental effects of environmental pollution. (mod. auth. abst.)
