Detailed explanation-1: -Populations are made up of members of the same species that interbreed. Population geneticists study the variation that naturally occurs among the genes within a population. The collection of all the genes and the various alternate or allelic forms of those genes within a population is called its gene pool.

Detailed explanation-2: -A gene pool refers to the combination of all the genes (including alleles) present in a reproducing population or species. A large gene pool has extensive genomic diversity and is better able to withstand environmental challenges.

Detailed explanation-3: -Population genetics is the study of genetic variation within and among populations and the evolutionary factors that explain this variation. Its foundation is the Hardy-Weinberg law, which is maintained as long as population size is large, mating is at random, and mutation, selection and migration are negligible.

Detailed explanation-4: -The key difference between genome and gene pool is that the genome refers to the entire DNA of an organism while the gene pool refers to the complete set of unique genes of an interbreeding population. Gene is the basic structural unit of the heredity. Genes pass from parent to offspring via gametes.
