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.
In prophase of mitosis the sister chromatids prepare to be separated into two daughter cells. Mitosis creates two daughter cells that each contain the same number of chromosomâ¦es as the parent cell. (2n) In prophase I of meiosis, the homologous chromosomes prepare to be separated. Meiosis I produces two daughter cells with 1/2 the number of chromosomes of the parent cell. Prophase II of meiosis is very similar to prophase of mitosis. In prophase II, the sister chromatids prepare to separate.
