Which of the following traits would likely be an example of sexual selection?

Bright plumage in male birds serves as a classic example of sexual selection. This trait often evolves because it provides a competitive advantage in attracting mates. In many bird species, females tend to prefer males with more vibrant and elaborate plumage, which signals health and vitality. These visual traits can indicate genetic quality, making them advantageous during mate choice. As a result, males with brighter plumage are more likely to reproduce and pass on these traits to their offspring. This dynamic illustrates how sexual selection influences the evolution of specific traits that are directly related to reproductive success rather than survival alone.
