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). WebMeiosis sets the stage for Mendelian genetics. Students need to know that most of the genetics action occurs in the first meiotic division: homologous chromosomes pair up and align end-to-end (synapsis) in prophase I crossing over occurs between homologous chromosomes in prophase I, before chromosomes line up at the metaphase plate
