Q. What is correct about the anal cerci in a cockroach?

NTA AbhyasNTA Abhyas 2020Structural Organisation in Animals

Solution:

The abdomen in both male and female cockroaches consists of 10 segments. A pair of anal cerci are found in the 10th segment of both the sexes. They are joint filamentous structures that are sensitive to sound and vibrations.
Meanwhile, anal styles are a pair of short thread-like structures that help in copulation. These are found in males only.
