BIOL 112 Prelab Quiz 1 - Population Genetics

Bethany is working on her two-page summary for her lab report but is really crunched for time due to a biology lecture exam and another exam in chemistry. She notices that there are a number of old lab reports available online. She decides to synthesize a lab report by cutting bits out of other's old reports and wordsmithing them together. She then submits her report on time. Which of the following types of academic dishonesty did Bethany commit?

Plagiarism

Pipet tips that come into contact with blood should be disposed of in which container listed below?

Tip Biohazard Container

The scientist who connected sickle-cell anemia with an increased survival rate from malaria was which of the following?

Tony Allison

Check the boxes for what conditions are needed for either natural or sexual selection to occur. Variation in fitness or reproductive success Variation in environment Different phenotype are caused by different genotypes Random chance Variation in alleles/genotype Another gene under selection

Variation in fitness or reproductive success Different phenotype are caused by different genotypes Variation in alleles/genotype

Match the scenario with the most likely evolutionary process. 1. Frogs need a pool of water to lay their eggs. One year there is a drought cutting the available pools for egg-laying to 25% 2. Sea otters that can hold their breath longer can catch more clams and thus have more energy for growth and reproduction. 3. Some bats return to their roost every year to mate; however, a few individuals end up in a roost of another group of bats. 4. Smelling relies on a receptor that matches the detected particle. One individual is born with a new receptor that can detect a new particle. 5. Male sea lions fight each other to hold territory that females use. Females only mate while within these territories.

Which of the following situation(s) lead to fixation of an allele? A. Model parameters: Starting frequency of allele A1: 0.5. Starting frequency of allele A2: 0.5. Fitness of genotype A1A1: 1. Fitness of genotype A1A2: 0.9. Fitness of genotype A2A2: 0.8. No mutation. Fraction of migrants each generation: 0.05. Frequency of A1 in source populations: 0.9. No Drift. B. Model parameters: Starting frequency of allele A1: 1.0. Starting frequency of allele A2: 0.0. Fitness of genotype A1A1: 0.7. Fitness of genotype A1A2: 0..9. Fitness of genotype A2A2: 1.0. Mutation rate from A1 to A2: 0.001. Mutation rate from A2 to A1: 0.001. No migration. No Drift. C. Model parameters: Starting frequency of allele A1: 0.3. Starting frequency of allele A2: 0.7.

Amira, Jon, Brit and K'Shawn are all in the same lecture class together. The professor occasionally posts extra credit questions in class only for those in physical attendance. One day, Jon and K'Shawn decide to skip class to work on a chemisty assignment at home. During that day's class, the professor posts a bonus point question. Brit texts the access code to Jon and K'Shawn via their group chat. Which of the following types of academic dishonesty did Brit commit?

Complicity

Once an allele is fixed, what way(s) is/are available to add diversity to a population?

Gene Flow Mutation

Which factor, on its own, will ALWAYS lead to fixation of an allele?

Genetic Drift

Which of the following processes randomly effect (i.e. you cannot calculate the precise end result) the change in allelic frequencies over time?

Genetic Drift Mutation

The safety items needed for this lab period include:

Gloves Closed-toe shoes Goggles

James struggled in his first semester and ended up Q-dropping his BIOL111 class. He seems to have things turned around and is taking BIOL111 again in the spring semester. James did pretty well in lab his first time through, so when lab starts up, he just submits his old lab reports that he scored well on instead of redoing the assignment. Which of the following types of academic dishonesty did James commit?

Multiple submissions
