mitosis & meiosis

mitosis

a process where one cell divides into two identical cells

mitosis

the new cells have the exact same DNA as the original cell

meiosis

a process where one cell divides into four cells, each with half the DNA of the original

meiosis

DNA is shuffled and halved, so when sperm and egg join, the baby has the correct total DNA and a unique genetic combination
