mechanism that governs proper chromosome <b>segregation</b> in eukaryotic cells. Synapsis (also called syndesis) is the pairing of two homologous chromosomes

during ... Most of the cytoplasm is <b>segregated</b> into one daughter cell, which 
becomes the egg ... For example, predivision (the separation of chromatids 
before <b>anaphase</b>) in the first polar body can induce the formation of an aneuploid 
polar body. A bivalent is one pair of chromosomes (sister chromatids) in a tetrad. A tetrad is 
the association of two pairs of homologous chromosomes (4 sister chromatids) 
physically held together by at least one DNA crossover. This physical attachment 
allows for alignment and <b>segregation</b> of the ... At the meiotic <b>metaphase</b> I, the
