Revise reproduction, the genome and gene expression with BBC Bitesize for GCSE Combined Science, Edexcel While mitosis is used for the division of ordinary body cells to produce diploid (2n) daughter cells, meiosis is used to produce haploid gametes (sperm and egg cells). Cancerous tumours are either malignant or What happens during the second stage of division in meiosis? The chromosomes line up again in the centre of the cell and the arms of the chromosomes (chromatids) are pulled apart. The papers will test your knowledge and understanding of di erent topic areas and your ability to work scientifically. During meiosis, a diploid (2n) cell undergoes two divisions to reduce its chromosome number, resulting in four haploid (n) gametes with half the number of chromosomes.
