Heteromorphism of distal C-bands of differnet origin connected with the M2 bivalent was observed in four analysed species, i.e.Tettigonia cantans, Tettigonia viridissima, Tettigonia caudata and Tettigonia ussuriana.Study of the chiasma distribution showed that presence of heteromorphic segments significantly modified this pattern, and hiasma formed preferentially in the chromosomal region furthest from the heteromorphic segment.Additionally, in the M3 bivalent of Tettigoni cantans, in the L1 of Tettigonia viridissima, and in the X chromosome of Tettigonia cantans, Tettigonia viridissima and Tettigonia caudata variability of the distal segment was observed.
