Question

In disruptive selection, what mechanism pushes phenotypes away from the population mean and toward extreme ends?

Options

• Increased internal competition

• Alignment with optimal environmental conditions

• Gradual continuous directional shifts

• Elimination of phenotypic extremes

Answer 1

In disruptive selection, increased internal competition pushes phenotypes away from the population mean and towards the extreme phenotypic ends, favouring both extremes over intermediate forms.
