• Option B: Gene pool is defined as the combined alleles of all the individuals in a population, which matches the description in the question.
• Option C: Mutation rate is the frequency of new mutations in a population, not related to the combined alleles.
• Option D: Allele frequency is the proportion of a particular allele in a population, not the total combined alleles.
