The coordinated pattern of migration of neural crest cells from rhombomere 2 to the first pharyngeal arch,rhombomere 4 into the second arch,and rhombomere 6 into the third arch is correlated with precise expression patterns of which of the Hox gene families?

Question

Quizplus · Accepted Answer

The Hox-2 (Hox B) gene family is expressed in a pattern that corresponds to the migration of neural crest cells from rhombomere 2 to the first pharyngeal arch, rhombomere 4 into the second arch, and rhombomere 6 into the third arch. This indicates a possible role for Hox-2 genes in the specification of the identity of the pharyngeal arches.
