Geepers, there are three choices that are related here, the fourth is totally unrelated.
If you have done any searching on your own, you will know that having "only one X sex chromosome" for females is "Turner's syndrome."
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
To determine which option a doctor could most safely ignore when searching for the cause of Jennifer's problem, let's break down each option:
a. Nonproduction of estrogen: This could potentially be a cause of Jennifer's problem since estrogen plays a crucial role in menstruation. Therefore, the doctor should not ignore this option.
b. Importance of Jennifer having only one X sex chromosome: This is referring to Turner's syndrome, which is a chromosomal disorder affecting females. Turner's syndrome can lead to the absence or partial absence of menstruation. Therefore, the doctor should not ignore this option either.
c. Possibility of Turner's syndrome: As stated above, Turner's syndrome can cause the absence or partial absence of menstruation. This is an important possibility to consider, so the doctor should not ignore it.
d. Possibility of Huntington's disease: Huntington's disease is a genetic disorder that affects the brain and causes the progressive breakdown of nerve cells. It is not directly related to menstruation, so in the context of Jennifer's problem, the doctor could most safely ignore this option.
Therefore, the most appropriate answer is (d) the possibility of Huntington's disease.
