The karyotype of the grey seal Halichoerus grypus

Abstract

The somatic chromosomes of the grey seal, Halichoerus grypus Fabr., and their autoradiographic pattern were studied in cultures of lung tissue. An idiogram was made based on measurements of 6 male and 14 female cells. The chromosome number of the grey seal is 2n = 32. Some comments were made on the karyological interrelationships among the species so far studied of the family Phocidae. 1970 Hereditas
