why is decreased genetic variation in a species considered a negative impact of genetic technologies?\nit reduces the nutritional value of foods produced by these species.\nit produces crops that are more resistant to weed killer.\nit makes the species more susceptible to diseases.\nit results in foods with less desirable traits.
Answer
Brief Explanations:
Genetic variation provides a species with a diverse set of traits. When it is decreased, the species has fewer genetic - based defenses. Diseases can target the limited genetic makeup more easily, making the species more vulnerable.
Answer:
It makes the species more susceptible to diseases.
