WebMeiosis I is where 1 diploid parent cell divides into 2 haploid cells. Prophase: In this stage, homologous chromosomes pair up to form tetrads . The formation of tetrads is also called synapsis. Something very important about tetrads is that they enable the homologous chromosomes to exchange segments of DNA, a process called crossing over . WebMeiosis: Telophase l The cell divides into two cells during telophase I (Figure 11). The bundle of chromosomes may have a nuclear envelope develop around them. The germline cells in some organisms such as human females, go through the first four stages of meiosis prior to birth. The germline cells remain at telophase I for some time.
