Which of the following statements best describes courtship behaviors in animals?

Step 1: Analyze the question The question asks which statement best describes courtship behaviour in animals. We need the option that defines courtship accurately and completely.

Step 2: Explain the concept Courtship behaviour is a set of displays, signals and rituals that animals use before mating. Its purposes are to:

• Attract a mate
• Identify a member of the same species
• Show that the animal is fit and ready to mate
• Synchronise the readiness of both partners

Examples: the male peacock spreading its tail feathers, male birds singing, the dance of the stickleback fish, and the flashing of fireflies. Females also take part, for example by responding with postures, calls or acceptance signals, and in some species (such as some birds and insects) females perform displays too.

Step 3: Evaluate each option

• A. Wrong. Courtship is not only for males, and it is about attracting mates, not establishing dominance. Dominance is a separate social behaviour.
• B. Correct. It describes displays and rituals by both sexes to attract a mate. Courtship is typically a two-way exchange of signals.
• C. Wrong. It is not primarily done by females. In many species the males do the most conspicuous displaying.
• D. Wrong. Aggressive contests between males are rivalry or fighting behaviour. They may occur around mating, but they are not courtship itself.

Step 4: Answer The correct option is B.

Exam tip: Be wary of options with words like "solely" or "only" (as in A). Biology rarely works in such absolutes. Also remember: courtship means attracting and communicating with a mate, while aggression and dominance are different behaviours.
