Transferrin Polymorphism and Population Structure of the Weddell Seal Leptonychotes Weddelli ( Lesson )

Abstract

Variation in the electrophoretic mobility of the iron-binding serum protein transferrin has been reported by Naevdal (1966a) in the harp seal Pagophilus groenlandicus (Erxleben), and in a serum protein thought to be transferrin in the ringed seal Pusa hispida (Schreber) (Naevdal 1966b). Transferrin variation has also been found in southern fur seals Arctocephalus spp. of the Australasian region (Shaughnessy, unpublished data).
