Combined genetic information of all the members of a particular population is known as what?

• A. Genome
• B. Gene Pool
• C. Genotype
• D. Phenotype

Answer: (B)

Gene pool embodies the combined genetic information of all individuals in a population. It includes every gene present and the various alleles that exist across the population, along with their frequencies. This concept is fundamental in population genetics because it tracks how the genetic makeup of a group changes over generations due to forces like mutation, migration, genetic drift, and natural selection. By contrast, a genome refers to the complete set of genetic material of a single organism, not a whole population. A genotype is the specific alleles present in an individual, and a phenotype is the observable traits that result from the genotype interacting with the environment. So the term that best describes the combined genetic information of all members of a population is gene pool.
