Science Homework Help

I’m working on a biology question and need an explanation to help me understand better.

You are observing a chicken wing that has two tips in a mirror image pattern (shown below). What has most likely occurred in the embryonic limb bud?

Group of answer choices

The embryonic limb bud had only one small region of organizer tissue.

The side of the embryonic limb bud (that was opposite to the organizer tissue) was exposed to a chemical that caused the degradation of Patched (also known as Patches).

The side of the embryonic limb bud (that was opposite to the organizer tissue) was exposed to a chemical that caused ubiquitylation of phosphorylated Ci.

The embryonic limb bud did not develop any organizer tissues.
