Answer:
A. Survive environmental changes.
Explanation:
Genomics refers to the scientific study of genes (DNA) found in living organisms such as humans and animals.
A genome can be defined as the complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).
Deoxyribonucleic acid (DNA) is an organic complex-molecular structure found in all living organisms. It comprises of genes and is essentially the foundation block of all living organisms.
Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.
Simply stated, natural selection entails the survival of the fittest. Therefore, the species that are able to adapt to the environment will increase in number while the ones who can't adapt will die and go into extinction.
The characteristics which are consistent with the concept of natural selection includes;
I. More offspring are produced than can survive in an environment (overproduction of offspring). This ultimately implies that, the more offsprings that are reproduced by the parent organism, the more likely are they to survive.
II. There is genetic variation within populations. This simply means that there is a better chance of having good or beneficial traits being passed from the parent organism to her offsprings.
III. Organisms with beneficial variations are more likely to survive and reproduce, as well as passing on their genes to subsequent generations.
Hence, a population of living organisms with a large gene pool (gene diversification) is more favorably disposed to survive environmental changes than a species population having a small gene pool.
In conclusion, the higher the genetic makeup of a living organism, the higher are its chances of surviving environmental changes in the ecosystem.
