Once more into the Hump Day breach!
One wonders about all the implications of this science-y tidbit: Dad May Join Two Moms for Disease-Free Designer Babies. Excerpt:
A new technology aimed at eliminating genetic disease in newborns would combine the DNA of three people, instead of just two, to create a child, potentially redrawing ethical lines for designer babies.
The process works by replacing potentially variant DNA in the unfertilized eggs of a hopeful mother with disease-free genes from a donor. U.S. regulators today will begin weighing whether the procedure, used only in monkeys so far, is safe enough to be tested in humans.
Because the process would change only a small, specific part of genetic code, scientists say a baby would largely retain the physical characteristics of the parents. Still, DNA from all three — mother, father and donor — would remain with the child throughout a lifetime, opening questions about long-term effects for this generation, and potentially the next. Ethicists worry that allowing pre-birth gene manipulation may one day lead to build-to-order designer babies.
It takes some doing to wrap the brain around this one.
We’re only really beginning to unravel the mysteries of genetics. At the moment we can’t guess at what all may be possible – although a lot of ink and pixels have been burned up in speculation, both in fiction and non-fiction. Robert Heinlein’s entertaining work Friday is one such, the story of a genetically engineered superwoman trained as a combat courier. A common saying among the artificial humans in that work is this: “My mother was a test tube – my father was a knife.”
