Final answer:
The interphase, consisting of the G1, S, and G2 phases, typically occupies 90% of the time required for meiosis. This extensive phase allows the cell to grow, replicate DNA, and prepare for the meiotic divisions.
Step-by-step explanation:
The phase that typically occupies 90% of the time required for meiosis is the interphase, which consists of the G1, S, and G2 phases. This phase is crucial for preparing for meiosis I and II and is comprised of cell growth, DNA replication, and final preparations for meiosis.
During interphase, cells spend varying durations in the G1 phase, which could range from a few hours to several days, depending on cell type. The S phase, where DNA replication occurs, typically lasts between 8-10 hours. The G2 phase, meanwhile, usually takes about 5 hours and involves continued cell growth and finalization of preparations for meiosis.
The actual stages of meiosis – meiosis I and meiosis II – take up relatively less time when compared to interphase. For instance, the M phase in meiosis is significantly shorter than interphase, lasting about half an hour.
