The total number of genes present in a particular population, at a particular time is called:
Correct answer: D. Gene Pool
- A. Gene
- B. Genome
- C. Genotype
- D. Gene Pool
- E. Karyotype
Explanation
Gene pool refers to the sum total of all the genes, alleles, and their variations present in a population at a particular time. It includes all the genetic information and diversity available within a population. The gene pool of a population is subject to change due to various factors such as mutation, migration, genetic drift, and natural selection.

About Concept of Evolution
Evolution is the heritable change in populations over generations, driven by mutation, recombination, natural selection, genetic drift and reproductive isolation. Questions examine variation, adaptation, survival and reproduction, speciation, fossil and anatomical evidence, and the difference between individual acclimatization and evolutionary change in a population.
