#Unit 8. Inheritance Biology

The probability that their next child will be affected is 1 in 2.
The probability that each of their children will be affected is less than 1 in 2 because the parents of the man with achondroplasia are not affected.
The mother of these children has a sister with achondroplasia. This increases the risk that the children could be carriers.
If their third child is unaffected, then the probability that their fourth child will be affected is 1 in 8.
