Simulating many crosses

You will simulate 4000 children of Pp with Pp and check that about one in four has white flowers.

The idea. random.choice picks one letter from a parent. One letter from each parent, sorted, makes a child. A fixed seed makes the run repeat, so the checker can test it.

Your tasks.

1. Write child(mum, dad): one random letter from each parent, joined and sorted.
2. Set kids to a list of 4000 children of Pp with Pp.
3. Set share to the percent of the kids that are pp.
