Answer:
The correct answer would be a. the sum of all genetic traits in a population’s individuals at a given time.
A gene pool is defined as a sum total of all the genes present in an inter-breeding population at a specific time.
It includes all the alleles of all the loci within the genes of a interbreeding population or species.
The composition of the gene pool of a population can change with course of a time due to evolution.
A large and diverse gene pool enhances the ability of a population to adapt, survive and evolve in a nature.
Temperature, rainfall, and geological features would be the major abiotic factors that would determine plant distribution.
