Artificial selection to obtain cows yielding higher milk output represents:
| 1. | Directional, as it pushes the mean of the character in one direction |
| 2. | Disruptive, as it splits the population into two, one yielding higher output and the other lower output |
| 3. | Stabilizing followed by disruptive, as it stabilizes the population to produce higher-yielding cows |
| 4. | Stabilizing selection, as it stabilizes this character in the population |
