Bivalents align at metaphase plate stage
WebBivalents or tetrads (four chromatids) align on on the metaphase plate (the equator of the cell) and spindle fibres attach to the kinetichores; protein structures located at the centromeres. In this stage, the nuclear envelope has been fully disintegrated. Anaphase I . Disjunction occurs. This is when the mitotic spindles pull the tetrads apart ... WebSep 14, 2011 · Specifically, they help align homologous chromosomes on the metaphase plate during metaphase and then separate the chromosome pairs during anaphase. So by inhibiting the production of microtubules ...

WebAs shown in the below figure, during metaphase I, bivalents from either parent can align on either side of the cell. In an organism with two sets of chromosomes, there are four …
WebDuring metaphase I, a spindle apparatus forms and the paired chromosomes align along the equatorial pole of the cell. During anaphase I, the individual bivalents completely separate from each other; then homologous chromosomes, with their cognate centromere, are separated and drawn to opposite poles of the cell.
WebBivalents, each composed of two chromosomes (four chromatids) align at the metaphase plate. The orientation is random, with either parental homologue on a side. This means that there is a 50-50 chance for the daughter cells to get either the mother's or … Meiosis: Homologous chromosomes pair forming bivalents until anaphase I … This section is under development.

During metaphase, spindle fibers attach to the centromere of each pair of sister chromatids (see Figure below).The sister chromatids line up at the equator, or center, of the cell. This is also known as the metaphase plate. The spindle fibers ensure that sister chromatids will separate and go to different daughter cells when the cell divides. incentives certificates gas
