Document Summary
This assessment allows 30 minutes and has 12 questions. Each question is straightforward and has only one correct answer. There are no penalties for incorrect answers on any question. Which of the following processes tends to reduce levels of genetic variation within a population: mutation, negative frequency-dependent selection, genetic drift, gene flow (migration). Snapdragons are plants that have flower colour controlled by the r locus. You measure lifetime offspring (seedling) production in a large population of snapdragons and observe that on average, red-flowered individuals produce 20 seedlings during their lives; and pink-flowered individuals produce 30 seedlings during their lives. Before they hatch, embryos of some types of snake grow hindlimb buds; despite the fact that adult snakes do not have, or need, hind limbs. In the archie comic book series, two females (betty and veronica) often compete for archie"s affection. In real life males compete for access to females, not the other way around.
