Question:medium

Study the following and choose the incorrect statements
I. In stabilizing selection, the organisms with average phenotype are preserved, whereas extreme individuals of both sides are eliminated
II. Movement of genes from one population to the other is called directional selection
III. Centripetal selection operates when homogeneous environment changes into a heterogeneous type
IV. Genetic drift is related to small populations

Show Hint

{Types of Selection:}

{Stabilizing (Centripetal):} Favors Mean. Graph narrows.
{Directional:} Favors one extreme. Graph shifts.
{Disruptive (Centrifugal):} Favors both extremes. Graph forms two peaks.
