Abstract
Meiotic metaphases II from archival slides were studied in male house mice caught near Rome in a hybrid zone beta een a population with nine monomorph ic centric fusions (CD: 2n = 22) and one with the standard karyotype (2n = 40). The segregation pattern was investigated: it was found that chromosome s of the same form tended to cosegregate.
