• Each cell has pairs of chromosomes and the cells are usually genetically identical.

• Each cell has pairs of chromosomes and the cells are usually genetically different.

• Each cell has half the normal number of chromosomes and the cells are usually genetically identical.

• Each cell has half the normal number of chromosomes and the cells are usually genetically different.
