[Chromosomal phylogeny of four Meriones (Rodentia, Gerbillidae) species (author's transl)].

The karyotypes of four species of the genus Meriones (Rodentia, Gerbillidae) : M. tristrami, M. crassus, M. libycus and M. persicus are compared. About 20 chromosomal rearrangements separate these species into two groups. Robertsonian evolution, associated with inversions and fissions, appears to have occurred.
