1. Meiosis takes place in: a) Haploid cells only b) Diploid cells only c) Haploid or diploid cells d) Somatic cells e) None of the above 2. During meiosis I: a) Homologous chromosomes align and are joined through synapsis. b) Homologous chromosomes align independently at the metaphase plate, similar to what occurs during mitosis. c) Homologous chromosomes align and are held together only at their centromeres. d) Sister chromatids separate. e) B and d 3. If a nuclear gene is described as being “single-copy” in a eukaryotic genome, how many copies of the gene are present in a somatic cell in interphase prior to S phase? a) One b) Two c) Four d) One or two e) One or more 4.

Unformatted text preview: Genes A and C 5% recombinants Genes B and C 15% recombinants From these recombination measurements we can best conclude that: a) The gene loci must be positioned in the chromosome as in the adjacent figure (relative to the centromere and telomeres) b) The gene loci must be positioned in the chromosome as in the adjacent figure (relative to the centromere and telomeres) c) We can surmise the relative order of the three genes, but cannot determine their position in the chromosome. 5. If a gene is haplosufficient, the behavior of a null allele in a heterozygote (wild-type/null) would be predicted to be: a) Recessive b) Dominant c) Incompletely penetrant d) Variable in expressivity e) Codominant...

    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.
