background: Lizards often have bright coloration and in some species there is variation in coloration within populations. For the sake of simplicity, let’s assume that color is genetically determined by a single gene with two alleles that interact in a codominant fashion: r+r+ = red, r+r- = yellow, r-r- = white. Imagine there is a large population of these lizards where 1 in 200 lizards have the white coloration, 30 are yellow and the rest are red. A tsunami sweeps through the population! Although no lizards died, 10 random lizards were swept to a nearby island. One of these individuals is white while the rest were yellow. Over time, these individuals remain stuck on the island and form a new population. Eventually, 80% of this population has the white coloration. Assume that color does not affect fitness in either population. question: At the time of the founding of the smaller population, (when 1/10 were white, the rest yellow), what was the chance of fixation of the r- allele via genetic drift over many generations? Enter the number as a percentage with two decimal places.
