Vedclass · Answer

(D) This experiment is known as the Spemann-Mangold organizer experiment. The dorsal lip of the blastopore acts as the primary embryonic organizer. When this tissue is transplanted to a new location (like the ventral side) in another gastrula,it induces the surrounding host tissue to form a secondary embryonic axis. This results in the formation of a second notochord and neural tube,leading to the development of a secondary embryo (a Siamese twin) attached to the host.

When a small piece of the dorsal lip of the blastopore of a frog's early gastrula is transplanted into another gastrula of similar age at the ventral lip,the result is:
