Lw. Andersen et Hr. Siegismund, GENETIC-EVIDENCE FOR MIGRATION OF MALES BETWEEN SCHOOLS OF THE LONG-FINNED PILOT WHALE GLOBICEPHALA-MELAS, Marine ecology. Progress series, 105(1-2), 1994, pp. 1-7
The genetic variation at 3 polymorphic allozyme loci was investigated
in a population sample comprising approximately 650 individuals of the
long-finned pilot whale Globicephala melas caught in the Faroe Island
s. The sample consisted of pregnant females (carrying foetuses), non-p
regnant females and males. The genetic variation was analyzed with a s
election component analysis. At 2 of the loci the hypothesis of no mal
e reproductive selection was rejected. It was concluded that the fathe
rs of the foetuses differed genotypically from the males found in the
schools, indicating that males migrate between schools to mate.
