Q. Artificial selection to obtain cows vielding higher milk output represents :

1. stabilizing selection as it stabilizes this character in the population
2. directional as it pushes the mean of the character in one direction
3. disruptive as it splits the population into two, one yielding higher output and the other lower output.
4. stabilizing folloued by disruptive as it stabilizes the population to produce higher yield ing cows.
