Individuals with two copies of the faculty CF gene will show symptom of the condition. Among white europeons,the probability of being a carrier is 1/25. For a child whose parents are both carriers, the probability of inheriting a copy of the CF gene from both parents is 1/4. a)What is the probability that any two white Europeans planning to have a child together would both be carriers? b) What is the probability of the child having cystic fibrosis?
