The main features of meiosis are:
- the chromosomes are copied
- the cell divides twice, forming four gametes
1, parent cell 2, chromosomes make identical copies of themselves 3, similar chromosomes pair up 4, sections of DNA get swapped 5, pairs of chromosomes divide 6,chromosomes divide 7, 4 unidentical cells are formed
