...Martin Sodek; Kristina Kovacovicova; Martin Anger Chromosome segregation in mammalian oocytes is prone to errors causing aneuploidy with consequences such as precocious termination of development or severe developmental disorders. Aneuploidy also represents a serious problem in procedures utilizing...

... events concerning the search of the homologous partner, the control of number and distribution of chiasmata, the mechanism of pairing correction, and chromosome segregation are considered. Meiosis is a specialized cell division that is required to halve the chromosome complement, in organisms...

... of the reciprocal translocations on reproductive performance is a serious problem in pig industry. This deleterious effect is caused by abnormal chromosome segregation during meiotic anaphase I and the production of chromosomally unbalanced gametes. In the carriers, usually a cross-like quadrivalent is formed...

.... Angiosperms Chromosome segregation Meiosis Polyploidy Recombination Synaptonemal complex The significance of meiosis for inheritance and evolution was first recognized more than a century ago [Weismann, 1893]. Since that time, considerable progress has been made in deciphering the cytological...

...D. Clift; A.L. Marston During meiosis, DNA replication is followed by 2 successive chromosome segregation events, resulting in the production of gametes with a haploid number of chromosomes from a diploid precursor cell. Faithful chromosome segregation in meiosis requires that sister chromatid...

... look at the biological functions of a protein complex, named cohesin, which is the main protagonist in the regulation of sister chromatid cohesion during chromosome segregation in cell division. The establishment, maintenance and removal of sister chromatid cohesion is one of the most fascinating...

... that involve potentially large population targets and/or seem to affect chromosome segregation by previously unsuspected mechanisms: metals, possibly acting by epigenetic mechanisms; nano-sized particles that might directly interact with subcellular components of the mitotic and meiotic machineries; cytostatic...
