Microsporogenesis and meiotic abnormalities in the hybrid complex of Phlomis composita (Lamiaceae)
Botanical Journal of the Linnean Society, 2003The extent of chromosome structural differences such as permanent translocations and paracentric inversions has been studied in the hybrid complex of Phlomis composita and its putative parental taxa P. lychnitis and P. crinita. They are detected as meiotic abnormalities during microsporogenesis.

[Diagnosticum of abnormalities of plant meiotic division].
Tsitologiia, 2006Abnormalities of plant meiotic division leading to abnormal meiotic products are summarized schematically in the paper. Causes of formation of monads, abnormal diads, triads, pentads, polyads, etc. have been observed in meiosis with both successive and simultaneous cytokinesis.

[Effect of emotional stress on the frequency of meiotic abnormalities in male mice].
Genetika, 1986The effect of stress on the recombination frequencies at the 1st and 2nd chromosomes of male mice was shown earlier. The purpose of this work is the study of the stress effects on the behaviour of meiotic chromosomes. Male mice (A/He and DD/J inbred strains) were treated with acute immobilizing stress at different periods, prior to killing.
