A
Which is the definition of modularity?
Parts of an organism are distinct from one another but are interconnected

Allometry
What happens in response to the mutation of the gene Ultrabithorax?
Halters being placed in locations where they normally do not occur
What region of the Hox gene codes for the protein binding region?

in segments in the same order on the embryo of the melanogaster?
Genes are generally co-linear, meaning they are arranged the same on the chromosome as the
embryo
