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
