Answer:
See the answer below
Explanation:
If a major change happens in an environment and there is no organism among the population of organisms in that environment that have traits that allow them to continue to survive despite the change, it means that all the organisms within the population will be wiped out by the change.
Survival genes allow organisms to adapt to changes within their environment. Without these genes, any change to the environment would lead to the death of the organisms. Hence, if the entire population lacks survival/adaptive gene to counter a particular change in the environment, it means they will cease to exist in that environment.
