Sorry to quibble, but mother and child are neither genetically identical nor genetically dissimilar. The mother contributes her DNA to the fetus such that 1/2 of the fetal DNA is from the mother.henry quirk wrote: ↑Wed Dec 28, 2022 5:53 pmMother and child are genetically dissimilar. Complicated mechanisms prevent the mother's body from rejecting the child's body. The child is inside Mom, certainly is dependent on mom, but is not part of her in same way her heart or liver is part of her.Iwannaplato wrote: ↑Wed Dec 28, 2022 7:41 amI think actually cs should have stuck with 'part of you.'
And unlike her heart and liver, the child, if left alone in the womb, will naturally vacate the premises. It's not meant to stay there.
(again, I'm time-pressed...I'm doin' you an injustice with this response)
Also, there are flaws in the heart and liver analogy. All bodily organs are dependent on all other organs for their nourishment via the bloodstream which is oxygenated via the respiratory system and supplied with substrate via the digestive tract and detoxified via the kidneys and carried by blood vessels that are affected by endocrine substances under the influence of signals from the brain. All are necessary for the survival of the body.
The fetus is also dependent on all of the above, however, in contrast, the fetus is ejected like a parasite.
