Advances in assisted reproductive technology (ART) have begun to diminish the “genetic link in defining parentage.” Increasingly, legislatures and courts are recognizing the importance of “social parents,” who act as parents to children although possessing no genetic link. The author defines lesbian legal theory and then uses this critical method to examine the link, or lack thereof, between genetics and parenthood. Finally, she examines how ART and morphing social patterns are affecting the evolution of American family law.
