Un grupo de investigadores deseaba estudiar si la luz reflejada y transmitida por la gaita de los lagartijos aumentaba su brillantez
o mejoraba su contraste con los colores del fondo. La gaita es un
pedazo de piel que tienen los lagartijos debajo de la garganta
que puede ser de diversos colores. Los lagartijos abren y cierran
la gaita para llamar la atención a machos y hembras de su misma

¿Cuál de las siguientes es la variable dependiente de este
estudio?
