Karyotypic variation due to the centric (Robertsonian: Rb) fusion of chromosomes is a widespread phenomenon among small mammal species. In 1993, we described a house mouse chromosomal hybrid zone in Upper Valtellina (SO). Here, we found mice with 32 different karyotypes, including the standard, or all-acrocentric race (2n=40), four Rb races (2n=22-26) and 27 hybrid types (2n=23-29). This hybrid zone presents a unique opportunity to study the role of Rb fusions and races in speciation. We have been studying this dynamic hybrid system using a wide variety of techniques: karyology, histology, breeding, mark-recapture and DNA sequencing. All four Rb races appear to be closely related, but 40AA has probably been introduced recently into the valley.
