L211 Molecular Biology Midterm Exam 1 January 30, 2009 The correct answers are highlighted 1. The Law of Independent Segregation applies to which of the following? A. Different genes that are located on entirely different chromosomes B. Different alleles of the same gene C. Different genes that are located close together on the same chromosome D. Different genes that are located far apart on the same chromosome 2. Assume that a single gene is responsible for the color of a flower. The “A” allele is dominant and the “a” allele is recessive. AA and Aa flowers are red while aa flowers are white. Assuming normal Mendelian inheritance, what percent of the F1 progeny will be white if an Aa heterozygote is mated to an aa homozygote? A. 25% B. 50% C. 75% D. 100% 3. Using the information from question #2 and assuming normal Mendelian inheritance, what are the genotypes of the parents if the progeny are 50% AA and 50% Aa? A. AA and aa B. Aa only C. AA and Aa D. Aa and aa 4. The Law of Independent Assortment applies to which of the following? A. Different genes that are located on entirely different chromosomes B. Different alleles of the same gene C. Different genes that are located close together on the same chromosome D. Different genes that are located far apart on the same chromosome 5. For this question consider two genes (designated by the symbols A and B) that are located on different chromosomes. Assuming normal Mendelian inheritance, what percentage of the F1 progeny will be Aa Bb if Aa Bb and aa bb parents are mated to each other? A. 25% B. 50% C. 75% D. 100% 6. Which of the following is a true statement regarding genes that are located on the same chromosome? A. Genes located on the same chromosome are assorted independently from each other B. There is no correlation between recombination frequency and the distance between genetic loci C. All genes on the same chromosome are tightly linked and do not undergo recombination D. The recombination frequency is directly proportional to the distance between the two genes

7. When does the process of recombination take place? A. Meiosis II B. After cells have exited the cell cycle C. Meiosis I D. Mitosis 8. Which of the following theories or principles stated that genetic material traveled from all parts of the body to the germ cells (i.e. sperm and eggs)? A. Germ Plasm Theory B. Chromosomal Theory of Inheritance C. Theory of Pangenesis D. Mendelian Genetics 9. Which of the following pieces of equipment was instrumental in the establishment of Germ Plasm Theory and the Chromosomal Theory of Inheritance? A. Mass Spectrometer B. Microscope C. DNA Sequencer D. Gel Electrophoresis 10. Do Mendelian patterns of inheritance also apply to genes located on the sex chromosomes? A. yes
