| Genetic Drift simulation | ||
| a. What is genetic drift? How does chance affect allele frequencies in a population?
b. What is meant by fixation of an allele?
c. Go through the driftworm simulation. Answer the following questions from the simulation: Why is there no point in adding more generations after all the worms are one color (when an allele has become fixed)? At a population of 5, what is the mean number of generations until an allele becomes fixed? ( http://www.biology.arizona.edu/evolution/act/drift/about.html ) | ||
