The prevalence of CF carriers (meaning they carry one mutation) is 1 in 25 in the Caucasian population. Most people don't even know that they are carriers until they have a child with CF. That means that the CF allele can unknowingly be passed down through generations. Carriers are typically asymptomatic and there is evidence to support that the CF mutation protected our ancestors from fatal diseases. So natural selection actually played a role in the proliferation of CF carriers.
