1.. A certain large population is found to exhibit a frequency of 3% for an autosomal recessive trait, i.e. 3 people out of 100, on average, have the trait (assume 100% penetrance). Assuming the alleles are in Hardy-Weinberg equilibrium, calculate the expected carrier frequency. When actually tested, it was found that the carrier frequency was 15%. Suggest one possible explanation for this non-equilibrium value.

2. a. A biallelic locus, Aa, has allele frequencies of A = 80% and a=20% in a certain population. Another biallelic locus, Bb, has allele frequencies of B = 90% and b = 10% in the same population. Both loci are found to be in Hardy-Weinberg equilibrium. Calculate the expected percentages of each of the AA, Aa, aa, BB, Bb, and bb genotypes in the population.

AA= Aa= aa=

BB= Bb= bb=

b. A recessive digenic disorder (100% penetrant) occurs ONLY when one has the aabb genotype. It’s found that 15 people out of 10,000 in this population have the disorder. What would be the expected frequency of the disorder if the Aa locus and the Bb locus were segregating independently? Is the actual frequency significantly different from this?

3. A very rare disorder is shown to depend on the genotype at three unlinked autosomal loci, A/a, B/b and C/c and that to be affected one must be homozygous for the rare allele at all three loci, that is, aabbcc. The MZ twin disorder concordance is 100%, implying that the penetrance is 100%. Calculate the expected dizygotic twin concordance for presence of the affected trait, that is, if one DZ twin shows the trait, what is the chance that the 2nd twin will be affected? (Hint: because the trait is rare, assume that both parents are heterozygous for all three loci. This is NOT the probability that both twins are affected among all DZ twin pairs.)

Biology Essay Help. Complete 6 out of 8 questions in this Essay Section, required questions are: 1, 2, 3, 4, and 7. Alternate questions are 5a or 5b and 6a or 6b. Select one of each of these questions to answer

1. You scoop up a water sample from a local pond nearby, because you are curious about the possible microbes that might live there. After looking at several slides that held drops of the sample, you noticed two different kinds of cells: One kind was very small and had no separate internal structures; the other kind was much larger, and it contained several kinds of internal structures that were physically different from each other. Please name each cell and briefly describe their overall similarities and differences.

2. PKU (phenylketonuria) is an enzyme deficiency disease that only develops in individuals who are homozygous recessive for that gene. An individual with PKU has parents that do not have this disease. What is the parents’ genotype for the gene responsible for PKU? What is the probability that they may have another child with PKU? How many future children of the affected individual will be carriers? Explain your answers.

3. Humans share 99% of their genes with chimpanzees, 90% with mice, 50% with fruit flies, and 37% with celery. Please explain the evolutionary significance of these data.

4. Describe the major land biome where you live. How have human activities changed the landscape and how has this affected native species? Include specific examples.

5. The habitat of one species of tropical fish is red coral reefs. The large majority of the fish in this population are red. A few individual fish carry a mutation that prevents the production of the red pigment; as a result these individual fish are white. The temperature of the ocean where these fish live gets warmer and warmer over a 10 year period, and as a result the coral is bleached and turns white. Use what you have learned about natural selection to explain how this bleaching event may have affected the evolution this fish population (not including possible direct effects of warmer temperatures on the fish). Include the following terms in your explanation: differential reproduction, beneficial trait, allele frequency, selection pressure, evolution.

Alternative to question 5:

At the beginning of the spring, Dr. Betty Burner notices that there is an equal distribution of long and short stemmed the dandelions in her backyard. By the end of the summer she notices that the majority of the dandelions have short stems. This observation is an example of what biological principle? Develop a hypothesis as to why there was an increase in the proportion of the short stemmed dandelions within the population.

6. You have read that inorganic fertilizers contribute to water pollution and would like to make a switch from inorganic fertilizers to organic compost in your vegetable garden. A friend graciously gives you a truck load of his compost. As a good researcher and critical thinker you are not convinced that organic compost will yield the same results as the inorganic fertilizer you have used for years with good results. To draw your own conclusion based on scientific evidence you decide to conduct an experiment in your garden. State a good hypothesis, design an experiment (include test subjects, sample size, control(s), dependent and independent variables, type of data collected) and hypothetical results/conclusion. Does your conclusion support the hypothesis?

Alternative to question 6:

If researchers establish that Myrothecium verrucaria is an effective biological control agent against kudzu, they must then demonstrate that the pathogen will not harm desirable species such as soybeans (a close relative to kudzu). Describe an experiment that could fulfill this purpose, including all steps of the scientific method. Identify control(s), dependent and independent variables.

7. Use what you have learned about energy transfer in food chains and the second law of thermodynamics to explain why it is an environmentally good choice to eat a plant based diet. Include the following terms in your answer: producer, herbivore, omnivore, trophic level, resources and energy

1. All living organisms are made up of one or more cells.

2. Only living organisms are complex.

3. All living organisms reproduce by passing on specific genetic information to future generations.

4. Only living organisms are capable of movement.

5. Only living organisms (populations) are capable of evolving.

6. Only living organisms require an input of energy to drive cellular activities.

7. Only living organisms produce heat as a byproduct of chemical reactions.

8. All living organisms are dependent on a constant supply of oxygen for survival.

9. Only living organisms respond to external stimuli.

10. All living organisms grow by increasing cell size and/or cell number.

2. The formulation of a hypothesis is based on observations and refined by available information from past observations or research. Place the following statements in the appropriate sequence showing the progression from an observation to a testable hypothesis.

1. You notice that the bread you left on the counter has more mold on it than do the rolls that you put in the refrigerator.You notice that the bread you left on the counter has more mold on it than do the rolls that you put in the refrigerator.

2. Does temperature affect the growth of mold or is the difference in mold growth related to differences between the bread and the rolls?Does temperature affect the growth of mold or is the difference in mold growth related to differences between the bread and the rolls?

3. Bread placed in warmer temperatures should develop mold faster and more extensively than bread placed in colder temperatures.
