The mitotic and meiotic cell cycles
(A) In mitosis, diploid cells replicate chromosomes during S phase and segregate sister chromatids during M phase, so that diploid daughter cells are produced. (B) In meiosis, two chromosome-segregation phases, meiosis I and meiosis II, follow a single round of DNA replication during the premeiotic S phase. During meiosis I, homologous chromosomes (shown in red and blue) are segregated to opposite poles. Sister chromatids then segregate to opposite poles during meiosis II, which results in the formation of nonidentical haploid gametes. Note that the lengths of the cell-cycle stages are not drawn to scale.

hey mate here is the answer
In meiosis, the chromosom duplicate and homologous chromosomes exchange genetic informationduring the first division, called meiosis I. The daughter cells divide again in meiosis II, splitting up sister chromatids to form haploid gametes.
hope this helps you
