Spring DBA Questions

Module 5 DBA Questions

Question 1—What is the overall purpose of meiosis, and in what types of cells does it occur?

Question 2—Summarize Mendel’s law of independent assortment. What aspect of meiosis accounts for this law?

Question 3—Describe how you would solve the following problem:

What is the probability that two individuals of the genotype AaBb and aaBb will have any offspring with the genotype aabb?

Question 4—How does the environment play a role in gene expression? Give two examples in which this might occur.

Module 6 DBA Questions

Question 1—Describe the process of gene expression, from gene to protein, and how a gene affects the phenotype expressed by an organism.

Question 2—If 20% of the DNA in a guinea pig cell is adenine, what percentage is cytosine? Explain your answer in terms of base pairing.

Question 3—What are the differences between the 5’ and 3’ ends of a DNA strand, and what is the significance of these differences for DNA replication?

Module 7 DBA Questions

Question 1—What are some examples of conserved core processes, and what do they tell us about the ancestry of life on Earth?

Question 2—Describe one scientific hypothesis for the origin of life on Earth. What evidence is used to support this hypothesis?

Question 3—What is a phylogenetic tree, and how is it used to depict evolutionary history?

Question 4—Explain why genetic variation within a population is essential for evolution.

Question 5—How would the appearance of free oxygen in the atmosphere affect the types of cells present on the early Earth?

Question 6—In a population of grasshoppers, some individuals are brown and others are green. Presently, both phenotypes are equally fit. What could happen to change the relative fitness of the two phenotypes in the population? For example, what could cause brown individuals to show increased fitness relative to green individuals?

Question 7—Assume a population is in Hardy-Weinberg equilibrium for a given genetic trait. Explain how you would determine what proportion of individuals in the population is heterozygous for the gene if the frequency of the recessive allele is 2%.

Module 8 DBA Questions

Question 1—What are some abiotic and biotic factors that could affect the stability of a population?

Question 2—What are pheromones, and what purpose do they serve?

Question 3—Compare the reproductive strategies of r-selected and K-selected species.

Question 4—Describe two models used to predict population growth and explain what each of them tells us about population.

Question 5—Explain how the distribution of ecosystems changes over time by identifying large-scale events that have resulted in these changes in the past.

Question 6—Discuss how consequences of human actions affect biodiversity at local and global levels. Give some specific examples of human impact on these ecosystems and how these impacts affect biodiversity.
