Question

How have Hox genes contributed to the diversity of animal body plans?

Short answer

Hox genes are activated by a series of regulatory genes, and the proteins they encode control the expression of later genes.

Step-by-step solution

Introduction

Hox genes are a subset of animal genes that specifically contain homeobox sequences. The general body plan of an animal, including the number of body segments, the number and location of appendages, and the direction of the animal's head and tail, are all determined by this gene cluster.

The explanation for the answer.

The morphology of the individual can significantly change as a result of altered homeotic gene expression. Organ and body component placement can be impacted by hox genes. A fruit fly's limb placement or the spacing between a person's fingers could be altered by a Hox gene mutation or duplication.
