According to the map, which continents have the highest rates of cystic fibrosis?
Based on the information from the reading, explain why this is the case.
What causes cystic fibrosis?
Typically, a lethal genetic disorder is very rare. Cystic fibrosis, on the other hand, is the most common potentially lethal genetic disorder among Caucasians. Describe one hypothesis explaining why this is the case.
Fill in the Punnett square below to visualize the offspring of a cystic fibrosis carrier and a person who doesn't have cystic fibrosis and isn't a carrier. Use F to denote the normal allele and f to denote the mutated CFR allele.
