Résumé
Rb fusions between acrocentric chromosomes leading to metacentrics tend to become fixed during the chromosomal evolution in the common shrew. Using microsatellite markers preliminary results show that populations are only slightly subdivided and genetic drift seems not to play an important role for the fixation of metacentrics. A significant segregation distortion in favour of metacentric chromosomes was found during male meiosis. This suggests that cytological factors such as facilitated fusion between acrocentric chromosomes or choice-effects at the level of gametes are more likely to play a role for the chromosomal evolution in the common shrew.
