Question 1: Why is it hard to define a bacterial species? Question 2: Why can evolutionary pressures shift microbial population quickly?
When bacterial DNA is replicated, the closed-circles DNA of the two daughter genomes are interconnected, like links of a chain.
What are prions? a. misfolded versions of normal brain protein b. tiny molecules of RNA that infect plants c. viral DNA that has had to attach itself to the host genome d. viruses that invade bacteria

What are the causes, symptoms, and complications associated with Type I, Type II, and gestational diabetes (GD)? Compare for similarities and differences.
Flower color in the desert poppy is determined by two independent loci. At each locus, color is added to the flower. At the first locus, a dominant allele adds blue color to the flower.

How did the popular notion of evolution in the late 19th and early 20th centuries differ from Darwin's original notions and from the Modern Synthesis of Evolutionary Theory?
If you detect a deviation in genotype frequencies from that expected by the Hardy-Weinberg relation, what possible explanations should you consider for the differences?
What was Darwin's model for heredity, and how did it weaken his argument that natural selection was the only adequate explanation for adaptation?
Question 1: What is the Founder Effect? Give an example of a population that has experienced a Founder event in the recent past. Question 2: How does inbreeding affect a population? Does it cause the
What is Overdominance? How can it lead to a stable equilibrium frequency of an allele in a population?
What is the modern notion of fitness? What did Darwin mean by the phrase "Survival of the Fittest?"
Compare homologies and analogies before and after Darwin. (i.e., how did Darwin change our interpretations of homologies and analogies from those of Aristotle?)
