A) Yes, Jan should undergo genetic sequencing.
BRCA1/BRCA2 are the causes of 20-25% of all hereditary breast cancers, so if Jan's mother and sister both have breast cancer, then the odds are that she has BRCA1 as well.
B)
Pros: If she does have an abnormal BRCA1 gene, she can take steps to lower her risk of breast cancer.
Cons: The tests can incite discrimination towards her in the workplace, and having it known she has a risk for breast cancer can severely increase the cost of insurance.
C) Genetic sequencing could affect the frequency of genetic diseases because the test could point out --- I can't finish because I have to go. I'm so sorry, reask the url of this question and ask someone to finish. Have a nice day!

Answer:
Its false
Amphicoelias altus (from the gr. "Hollow character on both high sides") is the only known species of the extinct genus. Titoniense, in what is now North America. Amphicoelias is present in stratigraphic zone 6 of the Morrison Formation
It was also similar in size to Diplodocus, about 25 meters long. Although most scientists have used this data to distinguish Amphicoelias and Diplodocus as separate genera, at least one has suggested that Amphicoelias is probably the largest synonym for Diplodocus.3 Amphicoelias altus, was named by paleontologist Edward Drinker Cope in December of 1877, although it was not published until 1878, for an incomplete skeleton consisting of two vertebrae, a pubis, the hip, and a femur, bone of the upper leg.4 Cope also named a second species, A. fragillimus
