Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
All the genes of all members of a particular population make up the population’s
A
relative frequency
B
genotype.
C
phenotype.
D
gene pool.
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-3: -The gene pool of a population consists of all the copies of all the genes in that population.

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: -Populations evolve through genetic change. A population’s gene pool includes all the alleles of all the genes of all the individuals within it. A gene pool for a single gene includes all the alleles of that gene present in all individuals. Analysis of a gene pool can reveal variation which is not visible in phenotypes.
