Bivalents

... quite new here and I'm not quite sure if this is in the right place but here goes. Can someone please tell me during what phase of meiosis I the bivalents align along the equator of the cell? One book I have says they move towards the equator during late prophase I and then align during metaphase ...

... one centromere ie: 'X' or does it refer to 2 of the same chromosome ie: 'XX', if so than it can also be as 'II' (chromosome not replicated yet...) bivalents: refers to a pair of chromosome temporarily united. Does this mean 'X' or 'XX'? germ cell: are these gametes or are they precursor gametes, ...

... extensive structural variation in size, chromosome number, number and arrangement of genes, and number of genome copies per nucleus. Commonly, 17 bivalents will be found at meiosis I if a flowering plant has 34 somatic chromosomes in a cell. From the analysis of the genome sequence of Arabidopsis ...

flowering plant with a somatic chromosome number of 34, 16 bivalents at meiosis 1, one of which involve chromosomes very much longer than any of the others. what does it say?

... I'll tell you meisosis anyway :) It starts with 4 chromosomes in the prophase where all the homologous chromosomes come together and form up 2 bivalents and the centrioles seperate and form a spindle . next comes the metaphase, where the bivalents line up on the equator of the spindle. after ...
