Questions about the worth of a fetus are inherently tied up with the abortion debate, so let’s get the terminology straight.

A fertilized egg is not a fetus, it’s a zygote. When the zygote starts dividing, it becomes, not a fetus, but an embryo. The embryo becomes a fetus after nine weeks (which is usually called the 11th week of gestation).

The overwhelming majority (78.9%) of abortions are performed before the 11th week.

Since one of the choices references stem cells, I’ll also point out that a fetus is worth nothing in stem cells. It’s embryonic stem cells that are valuable, but they’re harvested from blastocysts — an extremely early stage of embryonic development (it’s only about a week after fertilization).

We’re surrounded by anti-abortion rhetoric that grotesquely misrepresents the facts. This question isn’t helping.
