对来自北象海豹（Mirounga angustirostris）（代表加利福尼亚和墨西哥的五个繁殖群）的血液样本进行了电泳调查，以了解反映潜在遗传差异的蛋白质变异。 24个位点编码的21个蛋白未发现多态性。这种统一的纯合性可能是上个世纪海豹捕猎者大量捕杀该物种所带来的等位基因固定的结果。
Blood samples from northern elephant seals (Mirounga angustirostris), representing five breeding colonies in California and Mexico, were surveyed electrophoretically for protein variation reflecting underlying genetic differences. No polymorphisms were found among 21 proteins encoded by 24 loci. This uniform homozygosity may be a consequence of fixation of alleles brought about by the decimation of this species by sealers in the last century.
