Mitosis = body cells ، occurs in all organisms except viruses
Meiosis =reproductive cells، occur only in animals ،plants ،and fungi
One time before Mitosis
One time before miosis
Mitosis = one division
Meiosis= two divisions
Mitosis = 2 daughter cells genetically identical
Meiosis = 4 daughter cells genetically di erent
Mitosis = 46 in each cell (called diploid daughter cell) Same parent cell
Meiosis = 23 in each cell (called haploid daughter cell) halved from parent cell
