Answer 2

The type of fertilisation takes place in a hen is internal fertilisation.

Explanation:

• In hen, after fertilisation process, the zygote divides to form embryo which travels down to oviduct.
• During that travel, many protective layers are formed around embryo. When this protective layer is fully formed, a hen lays egg.
• After laying egg, hens always sit on egg to provide the warmth for the embryo in egg.
• It takes 3 week for an embryo to develop into chick which later comes out of egg automatically.
• The embryo gets oxygen through protective layer, protection from albumen around embryo and food from egg yolk present around embryo.
