NEET BIOLOGY

Detailed explanation-1: -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 consists of all the genes and their different alleles, present in an interbreeding population. Evolution requires that allele frequencies change with time in populations. Reproductive isolation of populations can be temporal, behavioural or geographic.

Detailed explanation-3: -A population’s gene pool consists of all the genes of all the members of the population. For a given gene, the population is characterized by the frequency of different alleles in the gene pool.

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 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.
