Detailed karyotyupe information (the number, C-bands, NORs) of Tetigonia cantans, T.viridissima, T.caudata, and T.ussarina is given.Differences in mean chasma frequency and in the position of C-bands between species are discussed.

Karyotype (number, shape, chiasma frequency), C-band and AgNORs pattern of Gampsocleis glabra, G. ussuriensis, and G. sedacovi (represented by two subspecies, G. s. sedacovi and G. s. obscura) are reported. Differences in the chromosome number, mean chiasma frequency, and position of C-band (paracentromeric, interstitial, and distal) between species are discussed.

Detailed karyotype information (the number, shape, C-bands, NORs, and chiasmata) of Tachycines coreanus Yamasaki, 1969 from South Korea is given for the first time. The karyotype of this species with 2n male=49 (XO) possesses all acrocentric chromosomes.

The rate of seven meiotic stages (zygotene-pachytene, diplotene-diakinesis, metaphase I, anaphase I, metaphase II, anaphase II, and quartet) was studied in the jerboas Jaculus jaculus jaculus, Jaculus orientalis, and Allactaga tetradactyla, chiasma frequency and terminalization being examined only in J. jaculus and J. orientalis, and compared with the previous data concerning A. tetradactyla. Significant differences in the rate of meiosis, frequency of bivalent types, and frequency of interstitial and distal or terminal chiasmata per genome length were observed between A. tetradactyla and the two congeneric species J. jaculus and J. orientalis. Differences of these parameters among individuals within each species are also discussed in detail.
