• Only genetic factors influence the growth of organisms, not environmental factors.

• Environmental factors have no effect on the growth of organisms.

• Genetic factors are less important than environmental factors in organism growth.

The ethics of artificial selection (selective breeding, genetic engineering) and the societal impacts of humans changing the inheritance of desired traits in organisms are debated because:

• It raises concerns about unintended consequences and moral responsibility.

• It guarantees only positive outcomes for all species.

• It eliminates the need for natural evolution.

• It is universally accepted without controversy.
