Mitosis:Cell division for any cell to create new cells in order to grow or repair. Produces 2 daughter cells which are identical to the original cell.1)The 46 chromosomes in a cell duplicate to form 46 chromosomes which each consists of 2 chromatids bound by a centromere.2)The chromosomes move to the centre of the cell, the 2 chromatids of each chromosome split at the centromere, creating 92 chromosomes. 46 chromosomes go to either side of the cell. 3The cell splits creating 2 cells each with 46 chromosomes, they are both identical to the original cell.Meiosis Cell division for cell used in reproduction (germ cells), it creates 4 daughter cells that each have 23 chromosomes, none are the same as the original cell.1)46 chromosomes duplicate to form 46 chromosomes that consist of 2 sister chromatids bound with a centromere.2)The chromosomes pair with another chromosome from the other parent to form 23 homologous pairs, each homologous pair consists of 2 chromosomes (each chromosome consists of 2 sister chromatids)3)These 23 homologous pairs line up and exchange genetic material.4)These 23 homologous pairs split in the cell and form 46 chromosomes which have a mix of genetic material, half at each side of the cells.5)The cell splits and forms two cells with 23 chromosomes with a mix of genes.6)In each cell, the centromeres connecting the chromatids of the 23 chromosomes split producing 46 chromosomes at either side of the cell. 7)Both cell splits producing, in total, 4 gametes with 23 chromosomes each.
