Question

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

• A. Death of the graft tissue
• B. The host gastrula undergoes abnormal development
• C. The host gastrula remains normal and unaffected
• D. The graft tissue induces development of another notochord in the host
