Detailed explanation-1: -Definition. 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-2: -gene pool, sum of a population’s genetic material at a given time. The term typically is used in reference to a population made up of individuals of the same species and includes all genes and combinations of genes (sum of the alleles) in the population.
Detailed explanation-3: -The gene pool is the sum of all the alleles at all genes in a population.
Detailed explanation-4: -The collective set of all the alleles that exist within a population is referred to as its gene pool. Changes in the gene pool pave the way for species adaptation, the emergence of new species, and, ultimately, evolution.
Detailed explanation-5: -Allele Frequencies In a sexually reproducing species, each member of the population has two copies of each gene. Therefore, the total number of copies of each gene in the gene pool is 200.
