BIOL 2200 - Exam II Practice Questions with Complete Solutions Which of the following statements correctly answers how the large amount of genetic variation observed in prokaryotes arises? A) The mutation rate in prokaryotes is much higher than in eukaryotes. B) They have extremely short generation times and large populations.

What are the 4 postulates of the theory of evolution? Correct Answer-1. Individuals within populations are variable. 2. Variations are passed from parent to offspring. 3. Some individuals are more successful than others. 4. Survival of certain individuals is not random, but is due to heritable traits. What is relative fitness? Correct Answer-The contribution an individual makes to the gene pool relative to other contributions. What are the components of fitness? Correct Answer-1. Survi...
