Texas Dem state legislator: Modern science says there are six sexes

“The bill seems to think there are two,” said Mr. Talarico, who holds an M.A. in education policy from Harvard. “The one thing I want us to all be aware of recognize is that modern science obviously recognizes that there are many more than two biological sexes. In fact, there are six, which honestly, Rep. Hefner, surprised me, too.” He explained that there are “six really common biological sexes” based on X and Y chromosomes: Not just XX (female) and XY (male), but also single X, XXY, XYY and XXXY. “The point is that biologically speaking, scientifically speaking, sex is a spectrum, and oftentimes can be very ambiguous,” Mr. Talarico said.
