A) They define segmental regions in the embryo.
B) They define the anterior and posterior compartments of individual segments.
C) Mutations in these genes cause one body part to look like another.

Accepted Answer

This phenomenon is known as homeotic transformation, which illustrates the critical role of homeotic genes in determining the identity of body parts.
