Sec. 160.505. GENETIC TESTING RESULTS; REBUTTAL. (a) A man is rebuttably identified as the father of a child under this chapter if the genetic testing complies with this subchapter and the results disclose:

(1) that the man has at least a 99 percent probability of paternity, using a prior probability of 0.5, as calculated by using the combined paternity index obtained in the testing; and

(2) a combined paternity index of at least 100 to 1.

(b) A man identified as the father of a child under Subsection (a) may rebut the genetic testing results only by producing other genetic testing satisfying the requirements of this subchapter that:

(1) excludes the man as a genetic father of the child; or

(2) identifies another man as the possible father of the child.

(c) Except as otherwise provided by Section 160.510, if more than one man is identified by genetic testing as the possible father of the child, the court shall order each man to submit to further genetic testing to identify the genetic father.
