- Chloroplast
- Nucleus
- Mitochondria
- Microtubules
- An individual can evolve
- True
- False
- Which of the following are examples of evolution that can be observed in human life times?
- Inset species becomes pesticide-resistant
- Infectious disease gaining antibiotic resistance
- The transition from wild wolves to domestic dogs
- A & B only
- All of the above
- What is the smallest unit that can evolve?
- Family
- Individual
- Population
- Species
- A localized group of individuals capable of interbreeding and producing fertile offspring is a
- Species
- Family
- Population
- Community
- Which of the following is not a condition for Hardy-Weinberg equilibrium?
- Extremely large population size
- No gene flow
- Mutations must occur
- No natural selection occurs
- All of the above are conditions for Hardy-Weinberg equilibrium
- The ______species concept cannot be applied to asexual organisms
- Biological
- Morphological
- Anatomical
- Developmental
- In a population that is in Hardy-Weinberg equilibrium, the frequency of a recessive allele in the gene pool is .7. The frequency of organisms in this population with the homozygous dominant genotype will be:
- 49%
- 14%
- 21%
- 9%
- 7%
- If a population has the following genotype frequencies: AA = .42, Aa = .46, and aa = .12, what are the allele frequencies?
- A = .42, a =.12
- A = .6, a = .24
- A = .65, a = .35
- A = .76, a = .24
- None of the above
- Which of the following characteristics display quantitative inheritance?
- Height
- Hair Color
- Number of fingers
- A and C
- B and A
- In unicorns, BB results in blue manes, bb in pink manes, and the heterozygote in purple manes. If there are 360 blue-maned unicorns in a non-evolving population of 1000, how many pink-maned and purple-maned unicorns are there?
- 400 pink-maned, 240 purple-maned
- 160 pink-maned, 240 purple-maned
- 360 pink-maned, 280 purple-maned
- 160 pink-maned, 480 purple-maned
- Which of these is not an anti-predator mechanism?
- Camouflage
- Toxicity
- Spines
- Aposematism
- Mimicry
- All of the above are anti-predator mechanisms
- A skunk has bright white stripes that can be identified by predators to notify them of the skunk’s noxious smell. This is an example of:
- Mimicry
- Camouflage
- Aposematism
- Predator-prey relationships
- Which of these is not a limitation of Batesian mimicry?
- There must be an aposematic species nearby
- The organism will be noticed more by predators, which could be dangerous
- They cannot be more commonly encountered than the aposematic
- It is an anti-predator mechanism
- In peacocks, the male is usually known for having showier feathers than the peahen (female peacock). The males with the most attractive feathers, therefore, are more likely to attract mates and produce offspring. What is this an example of?
- Aposematism
- Genetic drift
- Sexual selection
- Convergent evolution
- This occurs when a few individuals become isolated from a larger population, establishing a new population whose gene pool differs from the original population?
- Bottleneck effect
- Founder effect
- Adam effect
- Translocation
- Genetic drift as a major impact on ______.
- Small populations
- Large population
- Centrosome
- Polar astrals
- The Hardy-Weinberg equation is represented by:
- q^3 +2pq + q^3=1
- q^2 +pq^2 +q^2=1
- q^2 +2pq+ q^2=1
- Migration tends to ______difference in allele frequency between population while ______genetic diversity within population.
- Decrease, increase
- Increase, decrease
