1. Imagine a population of 10,000 humans living on an isolated island. Every generation, an average of one individual is born with cystic fibrosis, a fatal genetic disease caused by a recessive allele (ie., individuals with the condition are cc, Cc individuals are unaffected, but carry the allele) What are the frequencies o ...continues
