What is the term for the posture a female in estrus stands when near a male?

• A. Receptive stance
• B. Heat
• C. Lordosis
• D. Polyestrus

Answer: (C)

Lordosis is the sexually receptive posture shown by a female in estrus when near a male. In this reflex, the female arches her back, elevates the hindquarters, and often tucks or directs the tail to the side to facilitate mounting. This behavior signals readiness to mate and is driven by hormonal and sensory cues from the male. While heat or estrus describe the reproductive phase in general, they don’t describe the specific posture, and polyestrus refers to a cycle pattern. Receptive stance is descriptive but not the standard term for this defined behavioral posture.
