Rule 35 of the Mississippi Rules of Civil Procedure provides in part:
"When the mental or physical condition (including the blood group) of a party or of a person in the custody or under the legal control of a party is in controversy, the court in which the action is pending may order the party to submit to a physical or mental examination by a suitably licensed or certified examiner or to produce for examination the person in the party's custody or legal control."
Rule 35(c) provides that in divorce, child custody, and other actions under Title 93 of the Mississippi Code of 1972, examinations are entirely within the discretion of the Chancery Judge.
