Question

Quizplus · Accepted Answer

The placenta is formed from both fetal tissues (derived from the trophectoderm) and maternal tissues (derived from the endometrium). The fetal portion contains cells of the chorion, while the maternal portion contains cells of the decidua. These tissues have different genetic origins, with the fetal tissue containing DNA from the developing embryo and the maternal tissue containing DNA from the mother.
