Detailed explanation-1: -A gene pool refers to the combination of all the genes (including alleles) present in a reproducing population or species.

Detailed explanation-2: -The gene pool is also called plant genetic resources (PGR) or germplasm which could be defined as the sum total of all the alleles influencing a wide range of characters (i.e., the collective hereditary genetic wealth) that a crop has acquired over millions of years under natural conditions.

Detailed explanation-3: -The combination of alleles that an organism carries constitutes its genotype. If the paired alleles are the same, the organism’s genotype is said to be homozygous for that trait; if they are different, the organism’s genotype is heterozygous.

Detailed explanation-4: -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-5: -The gene pool is the sum of all the alleles at all genes in a population.
