Imagine there is a co-dominant deleterious new mutation that arises in a population of size 1,000 diploid individuals. This mutation reduces fitness by 0.001 (s=0.001) in the heterozygous state. What is the probability that this mutation will become fixed in the population?

We're considering a fully recessive, deleterious (harmful) mutation (A2) at an allele frequency of q = 0.01 (one percent) in a large outbreeding population. Thus p(A1) = 0.99. 1. What is the population frequency of A2A2 homozygotes? 2. What is the population frequency of A1A2 heterozygotes? 3. Of all the A2 alleles in the population, what proportion are in heterozygotes? 4. And what proportion are in homozygotes? 5. Now, your country starts a policy of sterilizing all the affected individuals...
