Web11 jul. 2024 · Check out this overview of meiosis, featuring the meiosis I and II 3D models in Visible Biology! Meiosis consists of two rounds of division: meiosis I and meiosis II. Each round has a prophase, metaphase, anaphase, and telophase. Meiosis vs. mitosis. Image from A&P 6. Prophase I is, in my opinion, the coolest phase of meiosis. Web2 uur geleden · During meiosis, cells combine one round of DNA replication with two rounds of chromosome segregation, all of which is tightly regulated to ensure that gametes inherit the correct number of chromosomes. Errors in meiosis can lead to aneuploid gametes that cause infertility, birth defects and miscarriages [ 1 ].
