21. After mating, the fertilized eggs develop within the female's oviduct . 22. The oviduct is thin; the spermatheca is elongate with a short duct. 23. In placental mammals, fertilization typically occurs inside the female in the oviducts . 24. The females spawn by passing eggs from their oviducts . 25. Cystovaries characterize most teleosts, where the ovary lumen has continuity with the oviduct . 26. A short oviduct conducts to the ootype, which continues with the uterine tube. 27. The eggs are fertilised internally in the oviduct . 28. Egg cells travel through the oviduct to the fertilization chamber, where fertilization occur. 29. The constituent ovarioles lead to two oviducts , which converge into a single oviduct. 30. The constituent ovarioles lead to two oviducts, which converge into a single oviduct .
