Why can multiple alleles only be effectively studied in populations rather than individuals?

• A. Because individuals can only have two alleles for a given gene.
• B. Because populations provide a larger gene pool for observing allele variations.
• C. Because populations are more genetically stable than individuals.
• D. Because individuals do not undergo genetic mutations.

Answer: (B)

Verified step by step guidance

1. Understand the concept of alleles: Alleles are different forms of a gene that can exist at a specific locus. In diploid organisms, individuals typically have two alleles for each gene, one inherited from each parent.
2. Recognize the limitation in individuals: Since individuals can only possess two alleles for a given gene, studying multiple alleles within a single individual is not feasible. This limits the observation of genetic variation.
3. Explore genetic variation in populations: Populations consist of many individuals, each potentially carrying different alleles. This diversity allows for the study of multiple alleles and their frequencies within the population.
4. Consider the gene pool concept: A population's gene pool includes all the alleles present in the population. This larger pool provides a comprehensive view of genetic variation and allows for the study of multiple alleles.
5. Evaluate genetic stability: While individuals may undergo mutations, populations as a whole tend to maintain genetic stability over time, making them ideal for studying allele variations and evolutionary processes.
