Artificial selection to obtain cows yielding higher milk output represents
Stabilizing selection as it stabilizes this character in the population
Directional as it pushes the mean of the character in one direction
Disruptive as it splits the population into two one yielding higher output and the other lower output
Disruptive as it splits the population into two one yielding higher output and the other lower output
B.
Directional as it pushes the mean of the character in one direction
Artificial selection to obtain cow yielding higher milk output will shift the peak to one direction, hence, will be an example of Directional selection. In stabilizing selection, the organisms with the mean value of the trait are selected. In disruptive selection, both extremes get selected.
