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: negative frequency-dependent selection, gene flow (migration), mutation, genetic drift. In a hypothetical population of lizards, skin colour is controlled by the g locus. Individuals with genotype gg are green with black stripes. You observe 100 lizards and count 4 green, 64 black, and 32 green-and-black striped lizards. 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. Why do female humans sometimes compete over males: this is a fictional example.
