Yes, that is correct. The placenta is from the fetus. However, since it integrates with the mother and also becomes part of her body, I would say that it's just as much the mother's organ as it is the fetus's; it just has the genotype of the fetus. I'm not an expert in this field, so I don't know if other scientists actually consider it to be the mother's organ.
