Meiosis is a sexual cell reproduction
During sexual reproduction, two cells called gametes combine to form a new individual.
- Gametes only have one copy of each chromosome.
- This is because you have a cell from the mother and a cell from the father and still have the same number of chromosomes, for example the human body cells have 46 chromosomes.
- The new individual will have a mixture of two sets of chromosomes, so it will inherit features from the mother and the farther.
Process of meiosis:
- Before the cell starts to divide, it duplicates its DNA. one arm of each chromosome is an exact copy of the other arm.
- In the frst devision in meiosis, the chromosome pairs line up in the center of the cell.
- The pairs are then pulled apart, so each new cell only has one copy of each chromosome.
- In the second division the chromosomes line up again in the center of the cell.like mitosis the arms are pulled apart.
- You get four gametes each with only a single set of chromosomes in it.
