- Imagine that you are in your late 30s or early 40s and decide that you want a child. You realize that you’re at greater risk of having a child with Down’s Syndrome. What sorts of genetic screening are available today? If you find out that this child has this condition, do you think it’s appropriate to have an abortion? Why or why not? Question: Does elective abortion of fetuses with physical or other developmental disabilities have an effect on the perception of personhood, dignity, and rights in society? Explain.arrow_forwardSuppose that in the near future, you are a prenatal care provider. In the most recent ultrasound checkup on the expecting mother, you unfortunately found that the fetus is suffering a neural tube defect in the form of anencephaly. Seeing as the mother is still in the 12th week of pregnancy or the 1st trimester, the pregnancy can still be terminated via medical means. How would you explain to the parents the situation they are in?arrow_forwardWhat conditions can be detected using fetal ultrasonography, amniocentesis, and chorionic villi sampling?

Which genes, gene products, and hormones are involved in the sex differences? Which sex- related hormones are circulating in high concentrations in a pregnant woman compared to a nonpregnant woman? Do these hormones cross the placenta (if you are uncertain, consider hormone chemical class relative to membrane permeability to make an educated guess)? Assuming these hormones do cross the placenta, how do they affect the hormonal environment inside the fetus, and how does this relate to fetal reproductive development?arrow_forwardWhy would a drug be given an "X" pregnancy category? A) adverse effects shown in animals, but the benefits of therapy may outweigh the risks B) adverse effects shown in animals and there are not adequate studies in pregnant women C) Well controlled studies in pregnant women have shown risk to fetus D) Well controlled studies in women have failed to demonstrate risk to fetusarrow_forward
