Final answer:
In polygynous species, males usually choose their mates and females must comply. This is due to factors such as resource availability, genetic fitness, and male displays or courtship behaviors.
Step-by-step explanation:
In polygynous species of animals, males usually choose their mates, and females, because they are smaller and weaker, must comply. This statement is true. In polygynous mating systems, one male mates with multiple females. The male typically establishes a territory with abundant resources, and females are attracted to these resources and mate with the dominant male. The female's compliance in choosing the dominant male is often due to factors such as resource availability, genetic fitness, and male displays or courtship behaviors.
