|
|
Individuals will only create offspring well-suited to the climate change
|
|
|
The individuals would produce more offspring
|
|
|
Individuals better suited to the new climate will help less-suited individuals survive
|
|
|
Some individuals will posses traits better suited to the new climate and be more likely to pass them on
|
Detailed explanation-1: -Why would a population with a large amount of genetic variation be more likely to survive a severe climate change in its environment? Individuals will only create offspring well-suited to the climate change.
Detailed explanation-2: -A genetically diverse population of individuals is more likely to survive than a population of individuals with similar genetic makeup. Variation allows some individuals within a population to adapt to the changing environment and natural selection allows the expression of those beneficial traits to persist.
Detailed explanation-3: -Genetic variations that alter gene activity or protein function can introduce different traits in an organism. If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection).
Detailed explanation-4: -Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.
Detailed explanation-5: -a population with a lot of genetic variation would likely have more phenotypic variation; therefore, such a population would more likely have individuals that can adapt to a changing environment. mutation can result in new alleles on chromosomes.
