Question

Which of the following structures does not open into the genital chamber of female cockroaches?

• A. A single median oviduct
• B. Spermatheca
• C. A pair of anal cerci
• D. A pair of collateral glands

Answer 1

The correct option is A A single median oviduct

The genital pouch of female cockroach can be divided into two parts. The anterior smaller part containing the openings of female gonopore, pores of spermathecae and collateral glands is called genital chamber, while the larger posterior part in which ootheca is formed is called oothecal chamber or vestibulum. Oviduct doesn't open into the genital chamber.

So, the correct option is 'A single median oviduct'.
