In many ways, meiosis is a lot like mitosis the cell goes through similar stages and uses similar strategies to organize and separate chromosomes in meiosis.
The cell cycle actively dividing eukaryote cells pass through a series of stages known collectively as the cell cycle: two gap phases (g1 and g2) an s (for. B), each cell undergoing mitosis divides into two complete new cells that are usually b), meiosis produces cells that have a diploid number of chromosomes. Meiosis is the type of cell division that produces gametes unlike mitosis, meiosis is a reduction division – the chromosome number is halved from diploid.
