In general, sympatric speciation requires the action of _____ selection acting against hybrids.
A)disruptive
B)stabilizing
C)directional
D)artificial
E)ecological

Question

Quizplus · Accepted Answer

Disruptive selection is required for sympatric speciation because it favors extreme phenotypes and reduces the fitness of intermediate hybrids, leading to the divergence of two or more populations. Other types of selection (stabilizing, directional, ecological) do not necessarily lead to speciation in the absence of geographic isolation. Artificial selection is a human-driven process and not relevant to natural speciation.
