The correct answer is stabilizing selection reduces the amount of variation in a trait. disruptive selection increases the amount of variation in a trait.
Stabilizing selection is a type of natural selection in which genetic diversity decreases because natural selection favours an average phenotype and selects against extreme variations.
<span>
Disruptive selection is a type of natural selection in which extreme values for a trait are favoured over intermediate values, thus it increases genetic variance.</span>
I think the correct answer from the choices listed above is option B. During diffusion, when the concentration of molecules on both sides of a membrane is the same, the molecules will <span>stop moving across the membrane. This is because equilibrium has already been achieved and there is no more driving force which is the concentration gradient present.</span>
