Oh yes, forgot to tell you that 50% of the DNA and cells, etc. are the mother's. Actually more if you count the mitochondrial DNA, Ted. And the Uterus, blood supply and lungs and intestines, food eaten, etc. belong to the mother.
A total lie and you know it. The fetal DNA has genetic markers that identify it as the offsping of the father and mother, but the DNA itself is niether the mothers or the fathers. For that matter YOUR DNA has the same sort of genetic markers, yet your DNA identifies you and all your parts as an individual human being. Using your logic, you are half your mother and she should be able to kill you.
The uterus belongs to the mother, but not a single blood cell; lung or intestinal tissue belong to the mother. The food eaten by the mother does transfer through the placenta, but no cell of the mother actually enters the fetus. In fact, if the mothers' cells do get through the semipermeable membrane of the placenta, the fetus's life is endangered.
When Roe Vs. Wade was decided, there was reason to believe that a fetus isn't an individual human being. However, no scientific definition of life and species backs any argument that the fetus isn't a human being, or that it isn't alive.
Like all bigotry, it is only perpetuated through voluntary ignorance.
