Record #157518:

Molecular evidence for twinning in Weddell seals (Leptonychotes weddellii) / Thomas S. Gelatt, Corey S. Davis, Donald B. Siniff, Curtis Strobeck.

Title: Molecular evidence for twinning in Weddell seals (Leptonychotes weddellii) / Thomas S. Gelatt, Corey S. Davis, Donald B. Siniff, Curtis Strobeck.
Author(s): Gelatt, Thomas S.
Davis, Corey S.
Siniff, Donald B.
Strobeck, Curtis.
Date: 2001.
In: Journal of Mammalogy. (2001.), Vol. 82(2) (2001)
Abstract: Microsatellite genotyping used to determine genetic relatedness of seven apparent twin dyads of Weddell seals born in McMurdo Sound. No previous reports of genetic evidence for twinning in wild pinnipeds. Review of 14 years demographic data combined with pathological examinations, behavioural observations and molecular genetic evidence suggests that twinning is extremely rare in Weddell seals and that females do not wean both pups in the wild.
