WebbProphase I is further divided into sub-stages: Leptotene: In this stage, the initiation of chromosome condensation takes place and it attains a composite form. Zygotene: In this, the homologous chromosomes pairs, the process is called chromosomal synapsis. It is followed by the generation of a composite composition called the synaptonemal complex.

WebbMeiosis I - Key Takeaways. Meiosis I consists of fours stages: prophase I, metaphase I, anaphase I, and telophase I plus cytokinesis. Known as the reduction division, meiosis I produces two daughter cells, each with half the chromosome number of the parent cell and its copies (n + n). During prophase I of meiosis, the homologous chromosomes ... WebbCytokinesis. Cytokinesis is the process in which the cell actually divides into two. With the two nuclei already at opposite poles of the cell, the cell cytoplasm separates, and the cell pinches in the middle, ultimately leading to cleavage. In most cells, the mitotic spindle determines the site where the cell will begin to invaginate and split.
WebbIn prophase, the nucleolus disappears and chromosomes condense and become visible. In prometaphase, kinetochores appear at the centromeres and mitotic spindle microtubules attach to kinetochores.

Prophase, in both mitosis and meiosis, is recognized by the condensing of chromosomes and separation of the centrioles in the centrosome. This organelle controls the microtubules in the cell, and each centriole is one half of the organelle.
