(a) If the court finds there is reason to believe that an alleged genetic parent has an identical sibling and evidence that the sibling may be a genetic parent of the child, the court may order genetic testing of the sibling.

(b) If more than 1 sibling is identified under§ 8-506 of this title as a genetic parent of the child, the court may rely on nongenetic evidence to adjudicate which sibling is a genetic parent of the child.
