Re: Differences Between Mitosis and Meiosis, Help please

Essentially you are correct. During a meiotic cell division, homologous chromosomes form a tetrad during synapsis and undergo disjunction during Anaphase I, reducing the total chromosome number by half. During mitosis however, homologous chromosomes do not pair up. During anaphase ...
