NEET BIOLOGY

Detailed explanation-1: -The fact that genes exist in alternate forms, called alleles, forms the basis for the study of population genetics .

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: -5.3). 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-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 includes all of the genetic diversity of a particular species. The size of the gene pool can change. The gene pool gets larger when organisms have mutations that are passed to the next generation. The gene pool gets smaller when all of the organisms with a particular allele die before having offspring.
