- What would happen to the frequency of heterozygous carriers of sickle-cell anemia (with AS genotype) if mosquitoes were completely wiped out in a large region?Minotaur is only found in the Labyrinth on the island of Crete. The area is famous for its annual spectacle of "Minotaur run," where herds of Minotaur rush out of the Labyrinth to reach their breeding grounds on the beautiful Aegean seashore. A group of Olympian scientists discovered that the horn size of the Minotaur is controlled by a single locus, with HH individuals having the longest, the Hh the medium, and hh the shortest horns. It is further found that the long-horned individuals tend to be tangled up along the way during the annual migration out of the Labyrinth, such that only 80% of the HH individuals can make it out of the Labyrinth alive. Once outside the Labyrinth, the short-horned individuals tend to be less successful at finding food, thus 60% would die from starvation before the beginning of the breeding season. Since the Hh individualsâ horn size are just right, so all of them survive the annual challenge. Initially, the annual migration of Minotaur started out with…Minotaur is only found in the Labyrinth on the island of Crete.

- describe the most likely cause of a heritable phenotypic change in some members of a population of asexually reproducing organisms. Explain how repeated exposure of the artesunate-sensitive Plasmodium strain to increasing concentrations of artesunate led to the development of the artesunate-resistant Plasmodium strain.In a study, an undergraduate student discovered a new enzyme involved in the metabolism of serotonin. This enzyme is made up of 3 subunits of the same protein. To characterize this enzyme, the student used genetic approaches to induce mutations in the coding region of the gene that codes for this protein and performed crosses to measure the effects of genotypes on enzyme activity. A) Indicate directly in the diagram (via a bar graph) the predicted relationship between genotype and enzyme activity. (Al represents the wild-type allele, A2 represents the mutant allele). A2A2 A1A2 A1Α1 B) Explain the reasoning for your prediction. Enzyme ActivityGive typing answer with explanation and conclusion In a village in Quebec the frequency of a common mutant cystic fibrosis allele (CFcf) is approximately 0.025. What is the risk of a gamete carrying the mutant allele in this area?
- In the nematode C. elegans, homozygosity for the e mutant allele causes an extreme "uncoordinated" phenotype, where the worm completely loses its ability to move. Examination of 100 individuals with genotype e/e reveals that 60 mutant worm can't move at all, 35 show a very reduced ability to move, and the remaining 5 seem to have a completely wild-type phenotype with respect to movement ability. These observations suggest that e has O incomplete penetrance and variable expressivity O low expressivity and variable penetrance Ohigh expressivity and variable penetrance O high penetrance and incomplete expressivityd) The graph in Figure 2 shows the effect of light on the period of oestrus in two groups of female sheep. The females in the control group were subjected to the normal seasonal variation in day length. Partially through the first year of the experiment, sheep in the experimental group were subjected to reversed day-length cycle. The period of oestrus of each group of sheep is shown in solid bands above the graph (Figure 2). Control Periods of oestrus Experimental 20- Experimental 18- 16- 14- 12- 10- 8- 6- Control Jun Aug Oct Dec Feb Apr Jun Aug Oct Dec Feb Month FIGURE 2 Using information from the graph in Figure 2, answer the following questions: During what months does oestrus occur in each group? Give ONE advantage of this pattern of oestrus to the sheep in the control group. Explain your answer. What information can be deduced from this experiment. Length of daylight/hoursIn recent years, the country of Zambia in Africa has had increasing cases of malaria. If 8 % of the population is born with a severe form of sickle-cell anemia (ss), what percentage of the population will be more resistant to malaria because they are heterozygous (Ss) for the sickle-cell gene, under the Hardy-Weinberg assumption?
- To understand the genetic basis of locomotion in the diploid nematode Caenorhabditis elegans, recessive mutations were obtained, all making the worm “wiggle” ineffectually instead of moving with its usual smooth gliding motion. These mutations presumably affect the nervous or muscle systems. Twelve homozygous mutants were intercrossed, and the F1 hybrids were examined to see if they wiggled. The results were as follows, where a plus sign means that the F1 hybrid was wild type (gliding) and “w” means that the hybrid wiggled.a. Explain what this experiment was designed to test. b. Use this reasoning to assign genotypes to all 12 mutants. c. Explain why the phenotype of the F1 hybrids between mutants 1 and 2 differed from that of the hybrids between mutants 1 and 5In Figure 20-5, note that the difference in survival rates between AS and AA genotypes declines as children get older. Offer one possible explanation for this observationIn certain salamanders, the sex of a genetic female can be altered, changing her into a functional male; these salamanders are called sexreversed males. When a sex-reversed male is mated with a normal female, approximately 23 of the offspring are female and 13 are male. How is sex determined in these salamanders? Explain the results of this cross.
