In a wolf population, wild-type individuals have genotype T1 at a locus that gives them very white teeth. Now consider an ancient mutation that introduced a neutral allele, T2: individuals with T1T2 have somewhat less white teeth and those with T2T2 have substantially less white teeth. Although initially only found in one individual, after 100 generations T2 increased to a frequency of q = 0.02. After 500 generations, q = 0.2. Today, after 1000 generations, q = 0.6. Required:
What is the probability today that the neutral T2 will eventually become fixed in the population?
