Page 1 of 5 Sample Lab Test Questions 09W 1. Gel electrophoresis is conducted for the XYZ-2 locus for a sample of zebra mussels. Given the gel results shown below, which statements are CORRECT? i. The observed heterozygosity is 0.01 ii. XYZ-2 is a dimer. iii. The observed frequency of FF individuals is 0.5 iv. The expected number of SS individuals is 5 if the population is in genetic equilibrium. a. i only b. ii and iv c. i and iii d. iv only e. ii and iii 2. Two samples from a population of a diploid organism have a combined heterozygosity of 0.001. Which of the following hypotheses are not a realistic explanation of this result? i. The population is very small ii. There are actually two groups of organisms that look similar but have limited gene flow between them. iii. Heterozygotes have low fitness 3. The GDH-1 locus encodes a gene for tail feather length in a species of bird. A gel electrophoresis of the GDH-1 locus reveals that a population of this species is not at genetic equilibrium.

    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.
