If she has blue eyes, it's easy to understand. A person with blue eyes has a blue-eye gene from both mother and father. You have to have both in order to have blue eyes. If you have one brown-eye gene and one blue-eye gene, you will have brown eyes.
I'm assuming Patrick's father has brown eyes. If Patrick's mother has blue eyes, she passes on the blue-eye gene to all of her children. If Patrick's eyes are brown and his mother's eyes are blue, then Patrick has one blue-eye gene, and one brown-eye gene.
If Patrick's wife has blue eyes, then there is a 50/50 chance that any of Patrick's kids with her will have blue eyes. If Patrick's wife has brown eyes, she may have one blue-eye gene and one brown-eye gene. In which case, 1 of every four of their kids would have blue eyes and the rest would have brown.
