There are two basic twin types now, identical and fraternal, but a third type is the focus of a new discovery. The story of these one-of-a-kind twins begins after natural conception and an uncomplicated term pregnancy, when the newborns were brought to the attention of science because one is anatomically male and one has sexually ambiguous genitalia...
...think that the egg probably carried an X and one sperm an X, and one sperm a Y. It's possible that it is far more complicated than that. But that's the simplified explanation," says Souter. The twins have different proportions of male cells (XY) and female cells (XX), and are chimeric, meaning they have tissue with a diverse genetic make-up. Twin A, identified as a hermaphrodite, has 5% XY and 95% XX after genetic testing of the skin. Comparatively, Twin B, the male...
...urology and human genetics at the David Geffen School of Medicine at UCLA says: "You don't need to have 100% Y-chromosome to be male. If you have more than 15% of Y-chromosome in the gonads it's likely that you're going to be a male." Twin A, he adds, is ambiguous because the number of cells carrying a male-determining chromosome was not high enough to masculinize the twin. "They're both ambiguous, if you will, but only one is from a genital perspective." Vilain adds that people should retire the term hermaphrodite should use "intersex...
...latent conflict between the postmodern hydra’s twin heads of diversity and choice is therefore resolved quite neatly. Both diversity and choice serve a larger, if largely subconscious goal in the contemporary Academy: a full realization of existential equality...
Only after reading Jerry Kaplan's book on GO Corp.--a former tech high flyer that flamed out--did Alvelda realize the marketability of a concept contained in a chapter of his 1995 Ph.D. thesis. That concept begat MicroDisplay, his first start-up, that same year and united his twin passions: education and technology. "There is an aspect of education and communication that helps people to grow personally that I never anticipated as part of the corporate world," he says...
