- 3The cell splits(splitting the 'x' shaped chromosomes) to form two daughter cells each containing 46 chromosomes and DNA from both the mother and fatherthe chromosomes are no longer 'x' shaped
- 4Each of the two daughter cells, containing 46 chromosomes, organise and split evenly - each into 2 daughter cellsthere are 4 daughter cells called gametes, each containing 23 chromosomes
