Answer 2

Answer: over a long period of time  

Genetic diversity can be defined as the increase in abundance of different genes in the gene pool of a particular species. The more the diversity of genes in the gene pool the more potent will be the ability of the organisms to adapt and survive under adverse environmental conditions. The development of genetic diversity among the members of the species takes a long time in the course of evolution as the new genes develop in every successive generation.
