Question

Where is jelly deposited as a covering on the egg of frog?

• A. In the oviduct
• B. In the water during fertilisation
• C. In the water after fertilisation
• D. In the ovary

Answer 1

The correct option is A In the oviduct

In frogs, the vitellin membrane and an adhesive jelly coating, also known as tertiary egg membrane, surround the eggs. When passing from the oviduct, it is added to the egg. This jelly enables the egg to be easily trained. The capable sperm readily fertilizes the egg as it has the location of the jelly receptor. The frog egg on the animal pole has yolk on the vegetable pole and nucleus.
