Okla. Stat. tit. 10, § 10-7700-510: Testing of identical brother – Use of nongenetic

evidence.

A. The court may order genetic testing of a brother of a man

identified as the father of a child if the man is commonly believed

to have an identical brother and evidence suggests that the brother

may be the genetic father of the child.

B. If each brother satisfies the requirements as the identified

father of the child under Section 27 of this act without

consideration of another identical brother being identified as the

father of the child, the court may rely on nongenetic evidence to

adjudicate which brother is the father of the child.
