WebMeiosis follows a similar pattern, but with two rounds of cell division. The first round, known as meiosis I, involves the separation of homologous chromosomes (chromosomes that are similar in shape and size). The second round, meiosis II, involves the separation of sister chromatids (copies of the chromosomes produced during DNA replication).
