Okay, she didn't provide a bit of genetic programming and a few cells
More genetic impact than people realise...
Present in the endometrial fluid during the time of embryo implantation were multiple micro RNAs, which are the molecules that encode information for how the embryo’s (and ultimately the fetus’s and the child’s) genes will be expressed.
What this means is that it’s the gestational carrier’s DNA (because RNA is a portion of a person’s DNA) that effectively directs the embryo’s genetic development, because RNA affects genetic coding, decoding, regulation and expression. It’s the gestational carrier’s DNA, then, that influences the way the baby develops, because it’s her genetic material that helps determines which of the baby’s genes get turned on and off. The gestational carrier passes these micro RNAs to the embryo via chemical molecules in the endometrial fluid, and it’s thought that they can influence the activity levels of the baby’s genes throughout life.
but she did provide, the material and processes that made that baby, from her own blood and bone. Mothers are not incubators
Exactly. We're not sycamore trees and we don't photosynthesise. A baby isn't created by a chemical reaction with sunlight and chlorophyll.
Babies are built out of us. Out of our bodies.
Made from us, by us, of us.
And that's why I hate that word 'carrier'.
