all of the following are typical behaviors exhibited by a bitch in estrus except one. which of the following is not typical?
standing to allow for breeding by a male
lifting of the tail
locking to the male (\tie\) overnight
behaving friendly to a present male

Explanation:

For Question 25: Parasympathetic innervation causes vasodilation which increases blood - flow into the cavernous portions of the penis during sexual stimulation. Sympathetic innervation is more related to functions like ejaculation. CNS (central nervous system) is a general term and not the specific innervation for this process. Somatic innervation is related to voluntary muscle control and not this blood - flow mechanism.
For Question 26: A bitch in estrus will stand to allow breeding, lift her tail, and be friendly to a male. However, the "tie" during mating is a physiological process that occurs during copulation and not a pre - copulatory behavior that is typically exhibited as a sign of estrus.

Answer:

Question 25: B. parasympathetic
Question 26: C. Locking to the male ("tie") overnight
