A form of natural selection that increases mating success rather than survival is called?

• A. Intrasexual Selection
• B. Intersexual Selection
• C. Prezygotic Barrier
• D. Sexual Selection

Answer: (D)

Sexual selection is the form of natural selection that increases mating success rather than survival. It acts on traits that help an individual attract mates or win mating contests, even if those traits reduce survival. It has two main avenues: intrasexual selection, where individuals of the same sex compete for mates, and intersexual selection, where one sex choosier selects mates based on certain traits. A prezygotic barrier, by contrast, is a reproductive barrier that prevents mating or fertilization, not a trait that evolves to boost mating success. So the term that best fits is sexual selection.
