Quizplus · Accepted Answer

This is an example of sexual selection where different selection pressures lead to divergence in the traits of males. Some females prefer large males while others prefer small males, leading to the evolution of two distinct male phenotypes. Temporal isolation refers to reproductive isolation due to differences in the timing of reproduction, hybrid inviability is when hybrid offspring have reduced fitness, and allopatric speciation involves the formation of new species through geographic isolation. None of these concepts are directly applicable to the scenario described.
