Artificial selection to obtain cows yielding higher milk output represents
(A)directional selection, as it pushes the mean of the character in one directionCorrect
(B)disruptive selection, as it splits the population into two, one yielding higher output and the other lower output
(C)stabilizing selection, as it stabilizes the character in the population
(D)Stabilizing selection followed by disruptive selection, as it stabilizes the population to produce higher-yielding cows
Answer: (A)
Solution
Breeding cows specifically for higher milk output consistently pushes the population's milk-yield trait in one direction (ever higher), which is the hallmark
