Yes, that is the answer.
https://en.wikipedia.org/wiki/Biological_ornament
An animal may shake, lengthen, or spread out its ornament in order to get the attention of the opposite sex, which will in turn choose the most attractive one in order to sexually reproduce. Ornaments are most often observed in males and choosing an extravagantly ornamented male benefits females because the ornament displays “good genes” will be passed on to her offspring, increasing their own reproductive fitness. As Ronald Fisher noted, the male offspring will inherit the ornament while the female offspring will inherit the preference for said ornament, which can lead to a positive feedback loop known as a Fisherian runaway. These genes are considered “good” solely due to the fact that it will increase the likelihood that a female will be attracted to the male that carries them. These structures usually serve as sexual cues, which are sensory signals used lead to mating responses. Therefore, ornamental traits are often selected by mate choice.[1]
