WebMeiosis and mitosis are both preceded by one round of DNA replication; however, meiosis includes two nuclear divisions. The four daughter cells resulting from meiosis are haploid and genetically distinct. The daughter cells resulting from mitosis are diploid and identical to the parent cell. Concept in Action WebThe end product of meiosis is four genetically different daughter cells, all of which are haploid. The steps taken to arrive at this end-stage requires two nuclear divisions, meiosis I and meiosis II. Below, we will discuss these steps in detail. Note that there are many similarities between meiosis and mitosis, another form of cellular division.
