Unformatted text preview: drawn a diagram to help make this clear.] 3. A. If a population contains N individuals, and a new allele is produced due to a mutation, what is the initial frequency of that new allele? (1 pt). Since a diploid population of N individuals has a total of 2N alleles at a locus, and since a particular mutation is probably only going to occur on one chromosome in one individual during a generation, the mutated allele’s initial frequency is most likely to be 1/2N. B. If the allele is neutral, why would genetic drift be more likely cause the new allele to be lost from the population? (1 pt) Remember the probability of an allele going to fixation is simply its frequency in the population. Since the unmutated allele’s frequency (1 - 1/2N) is much higher than the mutated allele’s frequency, the most likely outcome of drift will be loss of the mutated allele....
