Question 3 of 4 4.0 Points In these sea urchins, neutral mutations occur at a rate of mu = 1/1000 per generation. After many generations at a population size of 10, do you expect to see much genetic variation in the population? Pick ONE BEST choice: A. Yes, because genetic drift is a very powerful force in this population. B. Yes, because the ability of new mutations to add variation is stronger than the force of genetic drift. C. Yes, because both drift and new mutations help add variation in this population. D. No, because the ability of new mutations to add variation is far less than the force of genetic drift. E. No, because natural selection will always cause one allele to go to fixation, resulting in little genetic variation. Reset Selection Mark for Review What's This? Question 4 of 4 4.0 Points Starting with the same population of 10 haploid sea urchins, where 1 has the W allele and 9 have the P allele, assume now that the W allele has a strong selective advantage. Sea urchin offspring with the W allele are 9 times more likely to survive than offspring with the P allele. What is the probability that the P allele will fix in the very next generation?
