Evolution Free Response Questions
Answer the following questions in essay form. Outline form is not acceptable. Labeled diagrams may be used to supplement discussion, but in no case will a diagram alone suffice. It is important that you read each question completely before you begin to write. Your answers may be hand written or typed. You may use your notes and textbook to answer the question, but you may not discuss or write the question with anyone else. You will receive a zero for the assignment if there is any evidence that this is not your own work.
1. Charles Darwin proposed that evolution by natural selection was the basis for the differences he saw in similar organisms as he traveled and collected specimens in South America and on the Galapagos Islands.
A. Explain the theory of evolution by natural selection as presented by Darwin.
B. Each of the following related to an aspect of evolution by natural selection. Explain three of the following.
Convergent evolution and similarities among species (ecological equivalents) in a particular biome (e.g. tundra, taiga, etc).
Natural selection and the formation of insecticide-resistant insects or antibiotic resistant bacteria
Speciation and isolation
Natural selection and behavior such as kinesis, fixed action pattern, dominance hierarchy, etc.
Natural selection and heterozygote advantage
2. Do the following with reference to the Hardy-Weinberg model.
A. Indicate the conditions under which allele frequencies (p and q) remain constant from one generation to the next.
B. Calculate, showing all work, the frequencies of the alleles and frequencies of the genotypes in a population of 100,000 rabbits of which 25,000 are white and 75,000 are agouti. (In rabbits the white color is due to a recessive allele, w, and agouti is due to a dominant allele, W.)
C. If the homozygous dominant condition were to become lethal, what would happen to the
