Chapter 8, Problem 2RQ

What is meant by biological evolution?

Which of the following genetic diseases is/are inherited as an autosomal recessive trait: phenylketonuria, Huntingtons disease, Tay-Sachs disease?

In which direction would an MRI scanner move to produce sequential images of the body in the frontal plane, and in which direction would an MRI scanner move to produce sequential images of the body in the sagittal plane?

How did archaic Homo sapiens differ from anatomically modern humans?

What is the genetic basis and phenotype for each of the following disorders (use proper genetic notation)? a. Edwards syndrome b. Patau syndrome c. Klinefelter syndrome d. Down syndrome

What additional biological questions can be answered if one has the complete sequence of an organisms genome as compared with the sequences of individual genes?

Theodor Boveri predicted that malignancies would often be associated with chromosomal mutation. What lines of evidence substantiate this prediction?

Which of the following gives rise to the skin cells? a. ectoderm b. endoderm c. mesoderm d. none of the above

One unexpected result of the sequencing of the human genome was the finding that mutations in a single gene can be responsible for multiple distinct disorders. For example, mutations in the RET gene can cause two different types of multiple endocrine neoplasias, familial medullary thyroid carcinoma, and Hirschsprung disease. How do you think mutations in a single gene can have such diverse effects?
