Experimental mutations in the timing of Hox gene expression cause lab mice to develop deformed limbs.This is an example of
A)evolution of a new gene to code for the new morphology.
B)homeosis.
C)heterochrony.
D)a change in spatial pattern of gene expression.

Question

Quizplus · Accepted Answer

Heterochrony refers to changes in the timing of developmental events, which in this case is the altered timing of Hox gene expression leading to limb deformities.
