A. 100–150 beats per minute
B. 250–350 beats per minute
C. 500–700 beats per minute
D. 1000–1200 beats per minute

Which sex of rat has a greater anogenital distance (AGD)?
A. Female (shorter AGD)
B. Male (longer AGD)
C. Both are equal
D. Depends on strain
Correct Answer: B
Rationale: Male rats have a distinctly longer anogenital distance
(distance between anus and genital papilla) compared to
females. This is used for sexing.
