In what stage of meiosis crossing-over occurs
Did you know?
WebMeiosis produces our sex cells or gametes (eggs in females and sperm in males). Meiosis can be divided into nine stages. These are divided between the first time the cell divides (meiosis I) and the second time it divides (meiosis II): Meiosis I. 1. Interphase: The DNA in the cell is copied resulting in two identical full sets of chromosomes. WebExplanation: The process of meiosis begins with the replication of DNA during the interphase stage. During prophase I, homologous chromosomes pair up and exchange segments of DNA in a process called crossing-over. This genetic recombination leads to the creation of unique genetic combinations in the daughter cells. View the full answer. …
