(a) If a person whose parentage is being determined under this chapter declines to submit to genetic testing ordered by the court, the court for that reason may adjudicate parentage contrary to the position of that person.
(b) Genetic testing of the person who gave birth to a child is not a condition precedent to testing the child and an individual whose parentage is being determined under this chapter. If the person who gave birth is unavailable or declines to submit to genetic testing, the court may order the testing of the child and every person whose genetic parentage is being adjudicated.
