Textbook Question
Chapter 23, Problem 4TYU
A genetic change that caused a certain Hox gene to be expressed along the tip of a vertebrate limb bud instead of farther back helped make possible the evolution of the tetrapod limb. This type of change is illustrative of
- A. the influence of environment on development.
- B. paedomorphosis.
- C. a change in a developmental gene or in its regulation that altered the spatial organization of body parts
- D. heterochrony.
