Problem

Which of the following is LEAST likely to be a health problem for someone with cystic fibrosis?

a. nutritional deficiencies
b. diabetes
c. frequent infections
d. obesity

The allele that causes cystic fibrosis is recessive. An individual who is heterozygous for cystic fibrosis

a. is a carrier.
b. cannot reproduce.
c. will have children who are all carriers of cystic fibrosis.
d. cannot have children with cystic fibrosis.

Sophie has cystic fibrosis. 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. 25%, because only one in four gametes will carry the bad gene
b. 50%, because there is a 50% chance that Sophie will pass along the bad gene
c. 100%, because Sophie has the condition
d. 75%, because Sophie has the condition but the father does not
e. 0%, because the child must receive the bad gene from both parents

Sophie's parents are carriers for cystic fibrosis. If Sophie has a brother or sister from the same parents, what are the chances that the sibling would have cystic fibrosis?

a. 50%
b. 100%
c. 75%
d. 25%
e. 0%
