Chapter 17, Problem 3AWK
Summary Introduction
To review:
A mutation that occurrs during fetal development is always fatal or not.
Introduction:
During fetus development, mutation may interfere with gene expression in the developing cells that may stop their differentiation process and or change their fate, which could be dangerous for the fetus and it may die.

Students have asked these similar questions
What causes most of the phenotypic abnormalities in someone with Down's Syndrome?
A) They have many gene mutations that produce nonfunctional proteins.
B) They express too much of some proteins during development.
C) Their cells cannot go through mitosis properly during development because they have an odd number of chromosomes.
D) Their chromosomes cannot pair during meiosis.
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.
If a male has fragile X syndrome, is his mother or father more likely to be a carrier for the disease? Why?

- A woman who is eight (8) weeks pregnant requests a direct test for Huntington’s disease on her fetus. She tells her geneticist that she wants the test because she recently discovered that there is a family history of the disease in her husband’s family. One of his parents is affected so he is at 50% risk of developing the condition. She is adamant that she does not want to give birth to a baby who is at risk of developing Huntington’s and says that the test will help her to ensure that this is not the case. In counseling, she reveals that she has discussed this issue several times with her husband but he has always said he is not willing to take a test. He does not want to know his status and is extremely anxious about the possibility that he might develop the condition.
