In meiosis I, chromosomes in a diploid cell resegregate, producing four haploid daughter cells. It is this step in meiosis that generates genetic diversity. Prophase I. DNA replication precedes the start of meiosis I. During prophase I, homologous chromosomes pair and form synapses, a step unique to meiosis. The paired chromosomes are called bivalents, and the formation of chiasmata caused by genetic recombination becomes apparent.
Then the cell goes through two consecutive rounds of nuclear divisions, termed meiosis I and meiosis II, according to the journal Nature. As a result, the overall process of meiosis produces four daughter cells from one single parent cell. Each daughter cell has half the number of chromosomes as the original parent cell. The mechanisms of mitosis and meiosis are very similar. Meiosis I. Prior to meiosis I, the duplicated chromosomes, also known as sister chromatids, fuse together.
