Toxins, new habitat and increased food supply cause genetic variation indirectly.
What is genetic variation?
Genetic variation is the differences variances in sequences of genes between organisms of the same species. This lead to natural selection which is what drive evolution of life.
The following can increase genetic variation indirectly; Toxins, new habitat and increased in supply of food.
- Toxins can cause mutation that is change in genetic content because it causes alterations in the genes of organisms when it is build up in the body.
- New habitat can also cause genetic variation because the organisms will try to develop features which will help it's to adapt to the new environment.
- Increased food supply also cause change in genetic variation.
Therefore, Toxins, new habitat and increased food supply cause genetic variation indirectly.
