Why is decreased genetic variation in a species considered a negative impact of genetic technologies?

A. It reduces the nutritional value of foods produced by these species.

B. It produces crops that are more resistant to weed killer.

C. It makes the species more susceptible to diseases.

D. It results in foods with less desirable traits.

It is C) !

Explanation:

I just took the test and that answer was correct <3

C. It makes the species more susceptible to diseases

Explanation:

During genetic variation, decrease or increase both can happen. This both can occur by natural mutation or human-made mutation. An increase in genetic variation usually improves a species character. This improvement can occur on many sides, such as resistance, better growth, better yield, etc.

But when a decrease happens in genetic variation, it causes harm to a species. A decrease in genetic variation means a reduction in the total character of any species.

As an example, now Wheat s is resistant to wheat blast disease. Somehow, a decrease occurs in genetic variation of Wheat. As a result, that Wheat will be susceptible to the wheat blast disease because it will lose it's resistant against that disease.

For this reason, decreased genetic variation in a species considered a negative impact of genetic technologies.
