Question

Artificial selection to obtain cows yielding high milk output represents

(a) stabilising selection as it stabilises this character in the population

(b) directional as it pushes the mean of the character in one direction

(c) disruptive as it splits the population into two, one yielding higher output and the other lower output

(d) stabilising followed by disruptive as stabilises the population of produce higher yielding cows

Answer 1

Correct Option (b) directional as it pushes the mean of the character in one direction

Explanation:

The directional selection leads to change in the phenotypic characters of a population in one direction. In the case of artificial selection, it is intentionally done to increase the milk production, so directional selection operates.
