Abstract

The karyotype of a mouse trapped in a hybrid zone between a Robertsonian (Rb) population (2 n=22) and a population with the standard karyotype (2 n=40-all-telocentrics) shows two Rb chromosomes with new arm compositions. We suggest that whole-arm reciprocal translocations between Rb chromosomes gave rise to the new chromosome constitution and that such events can greatly help in understanding house mouse karyotype diversification and chromosomal speciation.
