DISCREPANCY IN NUCLEAR MITOCHONDRIAL AND KARYOLOGICAL CHARACTERISTICS OF

DISCREPANCY IN NUCLEAR, MITOCHONDRIAL AND KARYOLOGICAL CHARACTERISTICS OF MUSCULUS SUBSPECIES IN PRIMORYE HYBRID ZONE Spiridonova L. N. Institute of Biology and Soil Science, Far East Branch, Russian Academy of Sciences, Vladivostok 690022, Russia; spiridonova@biosoil. ru

The aim of this investigations is: • Determination of congruence between taxon-specific markers on different inheritance systems (n-, mt-DNA and chromosomes) for revealing the pattern of real genetic structure of M. musculus in the extensive hybridization conditions in Primorye

The tasks of investigation are: • To study subspecific structure of wild mice on nuclear DNA level in Primorye hybrid zone with RAPD analysis; • To sequence control region of mt. DNA and identify subspecific haplotypes; • To compare molecular and karyological data for clear up real genetic structure of house mouse populations.

The map of the collecting grounds 76 samples from 9 places of Primorye were used as the research material The wild mice were collected by colleagues of our lab (Korobitsyna К. V. , Frisman L. V. , Yakimenko L. V. , Korablev V. P. , Pavlenko M. V. , Chelomina G. N. ) and me.

Conclusions: • the inconsistency in markers distribution of • • • different inheritance systems of wild mice was shown, that is the consequence of extensive introgressive hybridization in this region; in most cases genetic diversity revealed by n. DNA was higher than by mt. DNA and chromosomes; musculus mitochondrial haplotype (83%) predominates in all studied samples that fits to a pattern of absorption crossing; the tendency for conservation of subspecific features of M. musculus (61%) is observed in the nuclear genome.
