Anaphase 1 and anaphase 2 are two phases in the meiotic division of cells which produces gametes during the sexual reproduction. The main difference between anaphase 1 and 2 is that homologous chromosomes are separated during anaphase 1 whereas sister chromatids are separated …
WebOct 27, 2024 · Anaphase I is the third stage of meiosis I and follows prophase I and metaphase I.

WebApr 28, 2024 · One of the most significant Cdks is the Cdc-14 which is initially activated by being released into the nucleus from the nucleolus and exported to the cytoplasm. Its initial function is during the early stages of anaphase where it plays a key role in stabilizing the mitotic spindles and releasing more Cdc-14 into the nucleus where it becomes restricted. WebMitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a …
WebAnaphase I. In anaphase I of meiosis I the homologous chromosomes are pulled apart from each other. The homologs are cleaved by the enzyme separase to release the cohesin that held the homologous chromosome arms together. This allows the chiasmata to release and the homologs to move to opposite poles of the cell.

The phases of meiosis is divided into two; meiosis-I and meiosis-II.
