Question

A rancher wants to investigate the use of artificial selection in his cattle herd. Which of these options is an example of artificial selection?

A) Breed a cow that produces large quantities of milk with a bull that comes from a line of cattle with long lifespans.

B) Trace the family tree of a chicken that lays many eggs back through several generations.

C) Separate a population of rabbits and monitor any trait changes over the next few generations.

D) Choose one individual in a population of sheep to favor with food and shelter and see if it mates more.

Answer 1

Answer: The correct answer is A. Breed a cow that produces large quantities of milk with a bull that comes from a line of cattle with long lifespans.

Explanation: This answer makes the most since and it shows the use of artificial selection. Artificial selection is when humans breed selectively to develop certain traits they are looking for or want in an animal. (I took the test and this was the correct answer.)

Have a nice day! :)
