Abstract
The karyotype (chromosome morphology and G-banding pattern) was examin ed in 15 individuals of Sorex alpinus, the alpine shrew, collected in southwest Switzerland and neighbouring France. All three recorded chro mosome numbers, 2N = 58, 56 and 54, occur within Switzerland. It was f ound that this difference in chromosome number is due to Robertsonian polymorphism. Polymorphism in the number of acrocentric versus subtelo centric chromosomes may also occur.
