(ii) can you calculate the allele frequencies if you know the genotype frequencies? A. (i) = yes; (ii) = NO B. (i) = yes; (ii) = yes C. (i) = NO; (ii) = yes D. (i) = NO; (ii) = NO 3 (i) Non-disjunction during meiosis I in a human male can produce a sperm with the karyotype 24, XY (ii) Non-disjunction during meiosis II in a human male can produce a sperm with the karyotype 24, YY A. (i) = TRUE, (ii) = TRUE B. (i) = TRUE, (ii) = false C. (i) = false, (ii) = TRUE D. (i) = false, (ii) = false 4 (i) Every time a human cell divides, over 50 new mutations can be found in the daughter cells (ii) In every new kid, over 50 new mutations can be found when comparing them to their parents; however, most of these new mutations are probably silent A. (i) = TRUE, (ii) = TRUE B. (i) = TRUE, (ii) = false C. (i) = false, (ii) = TRUE D. (i) = false, (ii) = false 5 Which of the following does NOT occur during mitosis? A. Pairing and synapsis of homologous chromosomes B. Disjunction of sister chromatids C. chromosome condensation D. None of the above (A-C) happen during mitosis E. All of the above (A-C) happen during mitosis 6 What type of DNA damage do the following repair enzymes/pathways predominantly repair? I. uracil DNA glycosylase II. nucleotide excision repair A. I = misincorportions during replication II = bulky adducts such as pyrimidine dimers B. I = cytosine deaminations II = misincorportions during replication C. I = bulky adducts like pyrimidine dimers II = cytosine deaminations D. I = cytosine deaminations II = bulky adducts such as pyrimidine dimers E. I = misincorportions during replication II = mismatched bases 7 If we pick sperm from the same man and sequence the DNA in each of them, about how much do we expect them to differ at the level of nucleotide sequence? A. Less than 1 difference per 100,000 base pairs B. About 1 difference per 1000 base pairs C. About 1 difference per 100 base pairs D. About 1 difference per 10 base pairs E. About 1 difference per 2 base pairs, or 50%

Page 3 8 Which of the following (A-D) is TRUE of eugenics? If you think none are true, pick E. A. It is a pseudo-science that was practiced in Nazi Germany, but not in the United States. B. It has the potential rapidly eliminate low-fitness recessive alleles from the gene pool. C. U.S. eugenics laws were used to target behaviors such as alcoholism, “immoratlity”, or even repeated running away from home. D. Only a few dozen people were forcably sterilized in the U.S. as a result of eugenics laws. E. None of the above statements(A-D) are true. 9 Next three questions: The pedigree shows a genetic disease or trait segretating in a family. Do NOT assume the condition is rare, because it might not be. Which, if any, of the parent-child trio(s) rule out X-linked dominant inheritance? A. None of them B. More than one of them C. A-B-E D. A-B-D E. C-D-G 10 Which, if any, of the parent-child trios rules out X-linked recessive inheritance?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
