Gene Pool
|
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 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: -The three major gene pools are: primary, secondary, and tertiary.
Detailed explanation-4: -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-5: -Since there are two copies of each gene, there are two alleles, which may be the same or different.
