Final answer:
During cytokinesis in meiosis, a cleavage furrow facilitates the division of cells, resulting in two haploid daughter cells each with one set of duplicated chromosomes. This process contributes to genetic diversity and prepares the cells for meiosis II.
Step-by-step explanation:
The Cleavage Furrow and Formation of Haploid Cells
During the process of cytokinesis in meiosis, a cleavage furrow forms, facilitating the division of cytoplasm into two daughter cells. Following the separation of sister chromatids during anaphase and their arrival at the cell poles, the chromatin begins to decondense as a new nuclear envelope encapsulates each nucleus. Consequently, two haploid daughter cells are produced, each carrying a single set of duplicated chromosomes, composed of one chromosome from each homologous pair.
Importantly, after telophase I and cytokinesis, the daughter cells are prepared to enter meiosis II without the replication of DNA. This ensures that each resulting cell contains a unique, haploid set of chromosomes due to the random assortment during the process, contributing to genetic diversity. The entire sequence of events underscores the fundamental mechanisms of genetic inheritance and cell division.
It's noteworthy that in other organisms, cytokinesis occurs without nuclear reformation, and for plant cells, a cell plate forms instead of a cleavage furrow to eventually create cell walls that divide the daughter cells.
