B)Sympatric speciation requires a selective disadvantage of hybrids (e.g., medium-billed birds)of two diverging populations.

Question

Quizplus · Accepted Answer

Sympatric speciation can occur without physical separation, but instead through various mechanisms such as disruptive selection or polyploidy. One mechanism of sympatric speciation is disruptive selection, which favors extreme phenotypes over intermediates. In this scenario, hybrids with intermediate traits would have a selective disadvantage, leading to the evolution and divergence of two separate populations.
