Which of the following is not a prediction of the neutral theory of molecular evolution? a. adaptive changes in dna sequences will occur faster in smaller populations b. the rate at which homologous dna sequences of two species accumulate base pair differences is roughly constant over long periods of time c. the rate of change in sequence is expected to be higher for nonfunctional dna sequences than for dna sequences whose protein products have critically important functions d. the probability that a new mutation will eventually be fixed in the population is about equal to 1/2ne, where ne is the effective population size e. the frequency of heterozygotes, averaged accross many dna sites, is higher if the population is larger
