Question

Describe an environmental factor that could
influence natural selection and decrease genetic
diversity. Pick a specific example to illustrate your
point

Answer 1

A lot of toxins in a coral reef could influence natural selection so it would become like survival of the fittest. Then the fish would develop certain traits to better protect themselves (less prey means predators would takes bigger measures to get food). This would also cause a decrease genetic variation because there wouldn't be as much fish left. Since the coral reef went from unique to dull from toxins.

Answer 2

Environmental factors like food availability and the introduction of predators could influence natural selection and decrease the genetic diversity of an ecosystem.

What is Genetic diversity?

Genetic diversity may be defined as the occurrence of biological variations within organisms of the same species.

Suppose take an example of deer. If the food availability for deer gradually decreases, the population of deer undergoes a considerable reduction. This may also influence natural selection.

Similarly, if the predators of deer are increased more in number, there must be a reduction in the genetic diversity of deer must be seen in that habitat.

Therefore, it is well described above.
