A scientist does an experiment in which she removes the offspring of rats from their mother at birth and has her genetics students feed and rear the offspring. Assuming that the students do not lick and groom the baby rats as the mother rats normally do, what long-term behavioral and epigenetic effects would you expect to see in the rats when they grow up?
What degree of differences would you expect to see in the DNA base sequences and epigenetic marks of monozygotic twins?
a. Similar differences in DNA base sequence and epigenetic marks
b. Greater differences in DNA base sequence than epigenetic marks
c. Greater differences in epigenetic marks than DNA base sequence
d. No differences in either DNA base sequence or epigenetic marks
Why is it difficult to study whether a trait is due to epigenetic changes or due to something else? (Hint: What are the other things that may cause disease?) (Minimum of 2 complete sentences.)

- Jan is concerned about using ART. She wants to be the genetic mother and have Darryl be the genetic father of any children they have. What methods of ART would you recommend to this couple? Jan, a 32-year-old woman, and her husband, Darryl, have been married for 7 years. They have attempted to have a baby on several occasions. Five years ago, they had a first-trimester miscarriage, followed by an ectopic pregnancy later the same year. Jan continued to see her OB/GYN physician for infertility problems but was very dissatisfied with the response. After four miscarriages, she went to see a fertility specialist, who diagnosed her with severe endometriosis and polycystic ovarian disease (detected by hormone studies). The infertility physician explained that these two conditions were hampering her ability to become pregnant and thus making her infertile. She referred Jan to a genetic counselor. At the appointment, the counselor explained to Jan that one form of endometriosis (MIM 131200) can be a genetic disorder, and that polycystic ovarian disease can also be a genetic disorder (MIM 184700) and is one of the most common reproductive disorders among women. The counselor recommended that a detailed family history of both Jan and Darryl would help establish whether Jans problems have a genetic component and whether any of her potential daughters would be at risk for one or both of these disorders. In the meantime, Jan is taking hormones, and she and Darryl are considering alternative modes of reproduction. Using the information in Figure 16.4, explain the reproductive options that are open to Jan and Darryl.arrow_forwardIs ethical to kill an unborn child with a deadly genetic disorder?

Now theywish to have another child and have informed their physician thatthey intend to greatly increase the amount of supplements theytake to increase the epigenetic effects in their child. The physiciancautioned them that studies available in human trials showno effect of choline on learning and that excess intake of folateduring pregnancy may be associated with an increased risk ofautism spectrum disorder in the child.
