Hox genes, can serve to regulate patterning of the body plan, and were ultimately responsible for major body plan changes including the evolution of terrestrial limbs from fins. (T/F)

True

Explanation:

Hox gene is responsible for giving form, shape or plan to body of an organism. These genes are set of transcription factor which specifies with in an organism's embryo which part will form a specific organ of the body. These are found at the 3' end of the DNA and are responsible for axial patterning. These genes are activated by regulatory genes and the proteins encoded at early stage expresses at the later stage.

Hence, the given statement is true
