WebMEIOSIS I: Homologous chromosomes separate. Prophase I: the nuclear envelope begins to breakdown and nuclear chromatin starts to condense into individual chromosomes made up of two sister chromatids. Metaphase I: pairs of homologous chromosomes (called tetrads) move along their microtubule attachments so they are lined up along the … WebIn both metaphase I and metaphase the chromosomes line up on the metaphase plate, but, in metaphase I the homologous pairs of chromosomes line up.

Web9 jun. 2009 · Meiosis has: (i) a succession of two rounds of division following a single replication, (ii) recombination, and (iii) co-segregation of sister chromatids at the first division. In this study, we identified a gene that controls one of these three features— entry into the second meiotic division—in the sexual plant Arabidopsis thaliana. WebMeiosis: Metaphase I Metaphase I starts when the tetrads are at the center of the cell (Figure 9). The tetrads have stayed together which insures that during the first division, each cell will get one chromosome from each homologous pair. WebAnswer and Explanation: 1.
