title: [Repetitive DNA, chromosome polymorphism and speciation of gerbils].
abstract: Restriction analysis of DNA and differential staining of chromosomes in three species of the genus Meriones: M. tristrami. M. meridianus. M. inguiculatus was carried out. High extent of homology of the genomes under study was found at the molecular and chromosomal levels. Speciation of M. tristrami followed by numerous fissions of metacentric chromosomes is assumed to be connected with appearance of the short BspRI sequence. Possible mechanisms of the mammal genome evolution are discussed.
