Which term refers to all the different genes contained in all members of a population?

• A. Genotype
• B. Gene pool
• C. Allele frequency
• D. Genome

Answer: (B)

Verified step by step guidance

1. Understand the key terms involved: 'Genotype' refers to the genetic makeup of an individual organism, 'Allele frequency' refers to how common a particular allele is in a population, and 'Genome' refers to all the genetic material of a single organism.
2. Recognize that the question asks about the collection of all different genes present in all members of a population, not just an individual.
3. Recall that the term 'Gene pool' is used in population genetics to describe the complete set of different genes and their variants (alleles) found within a population.
4. Distinguish that 'Gene pool' encompasses genetic diversity at the population level, whereas 'Genotype' and 'Genome' are more individual-focused terms.
5. Conclude that the correct term for all the different genes contained in all members of a population is 'Gene pool'.
