q^6.8 imagine a population evolving by genetic drift, in which the frequency of the allele K is 0.1. What is the probability that at some point in the future allele K will drift to a frequency of 1.0? Express your answer as a number between 0 and 1.

Step 1Let's solve this population genetics problem step by step:
Step 2: Understand the Problem
- We have an allele K with an initial frequency of 0.1 - We want to find the probability that this allele will eventually reach a frequency of 1.0 (fixation) - This is a classic problem of genetic drift in population genetics
Final Answer
Key Insights: - This probability is independent of population size - Most alleles will eventually be lost, but a small fraction will become fixed - The probability of fixation equals the initial allele frequency
