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. WebIn meiosis two divisions take place which results in the formation of four haploid daughter cells. The two stages of meiosis are- Meiosis I- Homologous pairs of chromosomes separate during meiosis I. 2. Meiosis II- Sister chromatids are formed due to replication in ‘S’ phase are separated during Meiosis-II. Meiosis Diagram
