Industrial melanism b. DDT resistance in insects c. sickle cell anemia and malaria 2001 Charles Darwin proposed that evolution by natural selection was the basis for the differences that he saw in similar organisms as he traveled and collected specimens in South America and on the Galapagos Islands. a. b. Explain the theory of evolution by natural selection as presented by Darwin. Each of the following relates to an aspect of evolution by natural selection. Explain three of the following: Convergent evolution and the similarities among species (ecological equivalents) in a particular biome 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 Essay Sample 1 Describe the modern theory of evolution and discuss how it is supported by evidence from two of the following three areas a. population genetics b. molecular biology c. comparative anatomy and embryology Chapter 23 1989 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 the frequencies of the genotypes in a population of 100,000 rabbits, of which 25,000 are white (recessive, w) and 75,000 are agouti (dominant, W) c. If the homozygous dominant condition were to become lethal, what would happen to the allelic and genotypic frequencies in the rabbit population in 2 generations? 1997 In a laboratory population of diploid, sexually reproducing organisms a certain trait is studied. This trait is determined by a single autosomal gene is expressed as two phenotypes. A new population was created by crossing 51 pure-breeding (homozygous) dominant individuals with 49 pure-breeding (homozygous) recessive individuals. After four generations, the following results were obtained: Generation 1 2 3 4 5 a. b. c. Dominant 51 280 240 300 360 Recessive 49 0 80 100 120 Total 100 280 320 400 480 Identify an organism that might have been used to perform this experiment, and explain why this organism is a good choice for conducting this experiment. On the basis of the data, propose a hypothesis that explains the change in the phenotypic frequency between generation 1 and generation 3 Is there evidence indicating whether or not this population is in Hardy-Weinberg equilibrium? Explain. Chapter 24 Essay Sample 2 Define, discuss, and give an example of how each of the following isolating mechanisms contributes to speciation in organisms. a. geographical barriers b. ecological (including seasonal) isolation c. behavioral isolation d. polyploidy 1986 Describe the process of speciation. Include in your discussion the factors that may contribute to the maintenance of genetic isolation. Broad Based Concepts 1998 The evolutionary success of organisms depends on reproduction. Some groups of organisms reproduce asexually, some reproduce sexually, while others reproduce both sexually and asexually. a. Using THREE different organisms, give an example of one organism that reproduces sexually, one that reproduces sexually, and one that reproduces BOTH sexually and asexually. For each organism given as an example, describe two reproductive adaptations. These adaptations may be behavioral, structural, and/or functional. What environmental conditions would favor sexual reproduction? Explain. What environmental conditions would favor asexual reproduction? Explain. b. 2002 The complexity of structure and function varies widely across the animal kingdom. Despite this variation, animals exhibit common processes. These include the following: Transport of materials Response to stimuli Gas exchange Locomotion a. Choose two of the processes above and for each, describe the relevant structures and how they function to accomplish the process in the following phyla Cnideria (e.g., hydra, jellyfish) Annelida (e.g., earthworm) Chordata (e.g., mouse) Explain the adaptive (evolutionary) value(s) of the structural examples you described in part a b. 2004 Darwin is considered the “father of evolutionary biology”. Four of his contributions to the field of evolutionary biology are listed below. The nonconstancy of species Branching evolution, which implies the common descent of all species Occurrence of gradual changes in species Natural selection as the mechanism for evolution a. b. For EACH of the contributions listed above, discuss one example of supporting evidence. Darwin’s ideas have been enhanced and modified as new knowledge and technologies have become available. Discuss how TWO of the following have modified biologists’ interpretations of Darwin’s original contributions. Hardy-Weinberg equilibrium Punctuated equilibrium Genetic engineering
