A zygote won't "turn into" a hydatidiform mole. It will already be in such a condition.
No, it won't "already be in the condition". Its a zygote. A zygote is one cell. A hydatidiform mole is a multicellular structure.
A zygote won't turn into a person. He is already in that condition.
By your definition of a person. Since a hydatidiform mole originates from sperm and egg (and that was the basis of your definition of a person), why is it not a person?
Nothing you've said on this subject passes any sort of rational analysis. It's no surprise that very little of what you say can be easily understood.
What I've said is perfectly rational. You just don't like it.
Our position has biology on its side. Yours has a reliance upon the detection of a heartbeat.
No opinion on personhood has "biology on its side". There is no biological definition of a "person". You have to figure that out for yourself.
You're not very good at this biology stuff, are you?
You don't seem to be very good at biology or logic.
Did you get your PHD out of a weetbix packet?
I think you got your bioethics from a bumpersticker. Your "person" definition is so loose as to be useless.
No, that is not at all necessary. You have to either be lying about this or lying about knowing anything at all about biology.
Whenever you do a procedure in science, you can't start with EXACTLY what you need because something will go wrong and you will end up with nothing. A good proportion of eggs, sperm and the resulting zygotes will not be viable, so you always produce more than you need. The problem has actually gotten worse because fertility drugs have become more powerful and implantation more efficient leading to more leftover embryos.
Could you do IVF in such a way that you didn't have ANY leftover embryos? Maybe, but biology generally doesn't give you exactly what you need. You'll always be stuck with extras.
We already have, in the US alone, an estimated 500,000 spare frozen embryos.
