Can't wait to meet them and for them to meet each other! Since each pair of identical twins has identical DNA would both couple's children look the same? These types of twins are called monozygotic twins, which literally means they come from the same cell: 'mono' meaning one, and 'zygotic' meaning a fertilised cell. Since monozygotic twins developed from the same cell, they have identical DNA. Each of Tom and Jen's children would look different to the next — just like any brother or sister — and the same goes for Tim and Jan's children.

Their children wouldn't inherit identical traits from their parents because of a process called 'genetic recombination'. Genetic recombination occurs during a special type of cell division that forms egg or sperm cells, when the chromosomes swap their genes in a unique way, forming genetically unique eggs or sperm.

So, for example, because of this process of genetic recombination, all of Jen's eggs would be different from each other. When one of Jen's unique eggs comes together with one of Tom's unique sperm during fertilisation another form of genetic recombination , this produces a unique child.

Considering identical twins have the same genes, is there a possibility that the genes could recombine in the same way in an egg or a sperm so that the identical twin pairs have identical children? Not really.
