Answer: c. coordinate.
Explanation:
Coordinate genes are those genes which are responsible for the development of major coordinate axes in the embryo. These axis include the anterior posterior axis and dorsal and ventral axis. These genes are responsible for the development of front, rear, top and bottom portions of the embryo. A null mutation restricts the transcription and translation processes in a gene thus when the RNA is not produced then no functional protein is expected. If the null mutations occur in the coordinate genes than it will effect the embryonic development. This will interfere in the formation of anterior and posterior poles of the embryo.
