Web5 sep. 2024 · Two specialized cells, called gametes, are formed through meiosis, a process of cell division resulting in daughter cells with half the original cell’s genetic material. What is it called when chromosomes split into daughter cells? During meiosis, chromosomes will split into daughter cells randomly, making each gamete unique. WebMitosis is a type of cell division that occurs in somatic cells (body cells) and is responsible for growth, development, and repair of tissues. It results in the production of two genetically identical daughter cells that have the same number of chromosomes as the parent cell.

WebSpecialization of the chromosome segregation machinery for meiosis. In meiosis, two rounds of segregation follow a single round of replication (for a review, see Marston and Amon 2004). In the first meiotic division (meiosis I), homologous chromosomes segregate away from each other, and sister chromatids comigrate. Web4 jul. 2024 · Meiosis I is a unique cell division that occurs only in germ cells; meiosis II is similar to a mitotic division. Then, just before a germ cell enters meiosis, it duplicates its DNA so that the cell contains four DNA copies distributed between two pairs of homologous chromosomes.
