similarities between catfish egg and domestic fowl egg

1. Protective membranes: Both catfish and domestic fowl eggs are protected by multiple membranes that help to keep the egg contents from drying out or being invaded by pathogens.

2. Yolk: Both eggs contain a yolk that provides the embryo with nutrients during development.

3. Chalaza: Both eggs have chalaza, which are twisted strands of protein that hold the yolk in place and provide it with stability during development.

4. Germinal disc: Both eggs have a germinal disc, which is the area of the egg where the embryo will develop.

5. Albumen: Both eggs have albumen, which is the egg white that surrounds the yolk and provides protection and support to the developing embryo.

6. Vitelline membrane: Both eggs have a vitelline membrane, which is a membrane that surrounds the yolk and separates it from the albumen.
