Name:_________________________ ID:__________________________ 1. Fill in the blank with the most appropriate description to the right (18): Allele: O A. A cross between an unknown genotype and a homozygote. Chargaff: R B. A cross between two heterozygous individuals. Trait: M C. A mistake the burnt something. DNA: U D. A value which a trait can take. Codominance: N E. Potentially results from the involvement of two genes in a biosynthetic pathway. Epistasis: E F. A cellular process allowing the maintenance of ploidy from one cell to the next. Transduction: I G. A process that can test if two individuals have a variant phenotype due to an allele of the same locus. H.A cross between an unknown genotype and a homozygous recessive. I. The process of DNA transfer in prokaryotes that involves a phage. Test Cross: H J. The process of mating between prokaryotes that involves an F plasmid. Complementation: G K. The process of DNA transfer in prokaryotes that involves naked DNA and electroshock therapy. L. The physical association of two genes upon a chromosome. M. A measurable aspect that can be used to describe an individual. N. A relationship between alleles of a single gene whereby you need multiple phenotypes to see this. O. A variant of a locus. P. A relationship between alleles of a single gene where the heterozygote is intermediate. Q. The physical association of one gene on the chromosome that determines gender. R. Identified symmetry within DNA. S. Used to transport genetic information that contains ribose, nucleic acids and phosphate. T. Used to transport genetic information that contains deoxyribose, nucleotides and phosphate. U. Chemical that contains genetic information and has a double helical structure. 2. The researcher studying sweaty flavored yeast in the Viticulture and Enology department identifies a number of NEW color variants and needs your help in their genetic analysis. All mutant lines were shown to be true breeding. To test the number of genes/complementation and the allelic relationships, the researcher crossed all of the mutants to each other and to the wildtype. (22).

    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.
