BIOS 195 Lab Exam 2
- What does it mean that populations are in Hardy-Weinberg Equilibrium?
- What are the five conditions of the H-W equilibrium?
- How does HW equilibrium relate to evolution?
- What is genetic drift?
- Does genetic drift affect small or large populations more?
- How does genetic drift effect endangered species managment?
- What is natural selection?
–Answer - there is no evolution happening in that population
–Answer No mutation. Random mating No gene flow Very large population size.No natural selection
–Answer If in HW equilibrium, its not evolving
–Answer random change in allele frequency
–Answer small
–Answer Endan- gered species have smaller population sizes, and due to genetic drift they may also have decreased fitness, increased susceptibility to disease and parasites, and an overall diminished ability to respond and adapt to environmental or biological stressors
–Answer mechanic of evolution 1 / 2

- What was the relationship between natural selection and the Rock Pocket Mouse?
- How was it that light vs dark mice were selected for or against in the Rock Pocket Mouse?
- Can the same mutation be advantageous in some environments but not in others?
- Did the appearance of dark-colored volcanic rock cause the mutation for black fur to
- How important was the environment in changing the frequency of the mutant (new) allele
- What forces of evolution have random components and which are not random?
- What is a peer-reviewed article?
- What is a model?
- What did we make with clay?
- What was the independent variable or what did you manipulate in the caterpillar
- / 2
–Answer natural selection acted on the rock pocket mouses color
–Answer when dark substrate was present natural selection selected for the dark mouse and vice versa
–Answer yes
appear in the rock pocket mouse population?–Answer it didn't cause the mutation but it increased the frequency of the allel
in a population of rock pocket mice?–Answer Very
–Answer genetic drift
–Answer an article read by a peer
–Answer a representation of an object or system
–Answer Caterpillars
