Replication and Distribution of DNA during Meiosis

WebDuring meiosis I, homologous chromosomes pair up with each other. When the homologs are divided into daughter cells, the chromosomes are sorted randomly into daughter cells. WebThe third part of the cell cycle is the G2 phase where the cell prepares for division. The G1, S and G2 phases together are called interphase. The M phase completes the cell cycle. ’M’ could be mitosis or meiosis depending on the type of cell. For the zygote, the goal is to make more somatic cells. Therefore, it goes through mitosis and ...
