Question

It has been found that the tenderness of beef can be predicted by analyzing a cow's genes. So, commercial tests are now available for farmers to be able to determine which of their cows possess the "tough" gene and which possess the "tender" gene. If a farmer routinely tests his cattle and only allows cows with the "tender" gene to mate, what is he doing?

Answer 1

Answer:

Selective breeding

Explanation:

On study island the 4 choices are:

A. selective breeding

 B. forensic testing

 C. recombinant DNA technology

 D. genetic bias

A is the correct answer because the farmer is "selecting" the type of cattle he wants and making more of that type of cattle.

Answer 2

This process is is called controlled breeding. This allows the farmer to breed the offspring in such a way that only the genes that he wants present are produced in the offspring.
