SUMMARY
The discussion centers on the probability of cystic fibrosis in the offspring of two carriers, Jane and Bill. It is established that if both parents are carriers, there is a 1/4 (25%) chance their child could inherit the condition. However, considering the uncertainty of both being carriers, the overall probability is calculated as 1/9. This is derived from multiplying the individual carrier probabilities (2/3) and the inheritance chance (1/4).
