The recent advent of so-called genome-wide association studies GWASswhich trawl through genetic data banks looking for gene variants statistically linked to traits, has both helped and hindered. He and Bellenson both say they did not intend to hurt anyone by making the app available.

Some studies suggested that a specific part of the X chromosome called the Xq28 region was associated with the sexual orientation of people who were biologically male — although subsequent research cast doubt on those results. It is not predictive. The published study emphasizes that the genetic markers cannot be used to predict sexual behavior.
