Question

The Animal Functional Genomics Laboratory at Mississippi State University conducts genetic research involving farm animals. The results can be used to genetically modify commercially useful animals. Which idea can BEST be used to argue in favor of this research? A) Genetic changes can be designed to make cows yield more milk. Eliminate B) Genetic changes can be used to create an entirely new species. C) Genetic changes can be used to control the populations of farm animals. D) Genetic changes can be designed to control the animals' group behavior.

Answer 1

Answer: (A) Genetic changes can be designed to make cows yield more milk.

Explanation: Milk yield per cow has more than doubled in the previous 40 years and many cows now produce more than 20,000 kg of milk per lactation due to genetic changes. This shows that genetic changes to make cows yield more milk has already occurred.
