Using the Punnett Square, answer the following questions:
- What is the probability a female offspring developing hemophilia?
- What is the probability of a female offspring being a carrier for hemophilia?
- What is the probability of a male offspring developing hemophilia?
- What is the probability of a male offspring being a carrier developing hemophilia?

- If this were about Cystic Fibrosis, how would the responses be different to the questions in the Initial Post? Give a detailed explanation supporting your response.
