If both the mother and the father are carriers for the cystic fibrosis gene, what are the chances that their child will be a cystic fibrosis carrier?

If a couple that are both heterozygous carriers of the cystic fibrosis allele have children, the chance that both their first and their second child are carriers is 0.5 x 0.5, or 25%, as determined by theMultiple choice question.

A healthy twenty-seven-year-old female presents to the physician for genetic counseling with her husband. They would like to become pregnant in the near future, but they have concerns that their offspring may develop cystic fibrosis. The wife’s sister has cystic fibrosis, an autosomal recessive disorder with an incidence of approximately 1 in 90,000. The husband’s history is noncontributory. What is the probability of the husband being a carrier?

3. If Sophie conceives a child, and the father neither has cystic fibrosis nor is a carrier, what are the chances that the child would have cystic fibrosis?a. 0%, because the child must receive the bad gene from both parentsb. 50%, because there is a 50% chance that Sophie will pass along the bad genec. 100%, because Sophie has the conditiond. 75%, because Sophie has the condition but the father does note. 25%, because only one in four gametes will carry the bad gene

Cystic fibrosis is caused by the inheritance of recessive alleles depicted by a lower case ‘c’.
