Considering we do not declare someone dead when their heart stops, but rather when the brain activity seizes, this is when the embryo should be protected. If we are allowed to "pull the plug" on an individual because of their level of brain activity, this should be the same for an embryo. Twins, who have the same genetics, are not considered the same person or clones because of their consciousness, which is what I believe determines personhood.

When someone is unconscious and does not have brain activity they don't simply stop being people, since we know that they will eventually wake up. For that reason a fetus, even without brain activity, should still be treated as a person, since, unless something actively goes wrong, they will "wake up" like an unconscious person
