NOTE: All answers must be detailed and fully address the questions asked, and must incorporate and reference, at minimum, the course materials. Brief and/or insufficient answers that do not reflect rigorous academic effort and college-level critical thought on the part of the student will receive little to no credit.
*If the question above presents questions in list (i.e. numbered) form, you MUST clearly label your answer in the given list form (i.e. use the same numbers provided) and address each question separately in order to receive credit.

1. Compare and contrast mutations and polymorphisms. Be specific and provide examples.
2. Explain the various ways that each of these can occur within a DNA sequence:
i. substitution
ii. deletion
iii. insertion
3. A female fruit fly who was not exposed to a mutagen, but whose father was exposed, mated with another non-exposed male (wild-type). All of their progeny seem normal, but there are twice as many female offspring compared to males.
i. Develop a testable hypothesis to explain these results.
ii. How could you test your hypothesis? Be specific.
4. Suppose you want to figure out what genes are involved in the production of proline (Pro) in a certain bacteria.
i. How would you go about designing a mutant screen to do so?
ii. Suppose your screen identified 5 mutants that barely grew without being given Pro in the medium. How would you go about determining the number of different genes these mutants represent?
5. Discuss the difference between the terms gene, transcription unit, locus and allele. Discuss within the context of what is presented in the course materials, and be specific.
6. If a certain species has more chromosomes than another species, does that mean it has
i. more DNA? Explain.
ii. more genes? Explain.
7a. (1) In people, the X chromosome is bigger than the Y chromosome. Does that mean females have more DNA than males? Explain.
7b. (2) What would happen if the SRY gene was moved to chromsome 2, adjacent to the LCT gene? Would SRY still be able to carry out is function? Why or why not? If no, what would be the consequences? Be specific.
8. Explain the difference between DNA, chromatin, and chromosomes, as presented in the content of this course.
