Ureters act as urinogenital ducts in

  1. human males
  2. human females
  3. both male and female frogs
  4. male frogs

Answer

(4) male frogs

Solution

As per NCERT, in male frogs the ureters act as urinogenital ducts – the vasa efferentia from the testes open into the Bidder's canal, which joins the ureter, and the ureter carries both urine and sperms into the cloaca.

⇒ In female frogs the ureters carry only urine; the oviducts open separately into the cloaca.

⇒ In human males the urethra (not the ureter) is the common urinogenital passage.

Answer: (4)
