- Entomologists at the New York State Department of Agriculture are interested in determiningthe connection between pest insects infesting crop plants with populations of the same insectinfesting native plants in natural habitats. Long term trapping and monitoring studies haveestimated that on average 3% of the populations move between habitats (farm to natural and visversa) each generation. A new insecticide resistance allele (∆K) has begun to increase infrequency in the agricultural populations. A genotyping survey at this locus of 50 individuals ineach population has revealed the following genotype counts: K/K K/∆K ∆K/∆K Agricultural field 32 16 2 Forest 48 2 0 4a. Based on the effects of migration alone, what will the frequency of ∆K be in the forestpopulation in the next generation? 4b. If migration was acting in here without selection, what would the frequency of ΔK be in theagricultural population in the next generation? 4c. If the natural forest population was…Disassortative mating is: Group of answer choices 1. between similar genotypes and increasing heterozygosity. 2. between similar genotypes and increases homozygosity. 3. between different genotypes and increases homozygosity. 4 Neither alters genotypic frequency nor allelic frequency. 5 between different genotypes and increases heterozygosity.This question is concerned with the extended concept of probability, including the application of binomial expansion.
- The above data are from a landmark student looking into the relationship between sickle cell anemia and malaria. These data are from a population where malaria is prevalent. A is the allele for normal red blood cells; S is the sickle cell allele (you should know what this means). Is this population in H-W equilibrium? Make sure to use chi-square. Why or why not (if not, what assumption(s) violated). Genotype AA AS SS Total Observed 9365 (75.6%) 2993 (24.2%) 29 (0.2%) 12,387Using the data on the segregation of eye-color from Dosophila culture (see table 1). Tabulate your F1 and F2 data on eye-color as associated with sex by making a table. Based on your observations, frame your hypothesis as to the expected segregation of eye-color associated with sex. Apply the Chi-squared test to determine the goodness of fit of your data per generation. Ho: Ha: Decision Criteria: If X2c < X2tab, accept Ho. Otherwise, fail to accept Ho and accept Ha. Fill-up the next table. Conclusion:1) Chi-square analysis generates a p value, an important indicator of statistical support for a hypothetical outcome. If a p value = 0.05 > p > 0.01, the tested hypothesis fails to be falsified. Agree/Disagree? Answer with explanation here:
- Design a simple, manipulative experiment to test the hypothesis that synthetic fertilizers in the environment influence the population density of the salamander, Ambystoma tigrinum. Your experiment can have no fewer than two treatments and no more than four. State your hypothesis. Briefly describe your experiment. Address the following: Is it a field or lab experiment? What are the treatments, how are they set up, and what differentiates them? How many replicates of each treatment will there be? What are the standardized conditions of your experiment? C. Identify the independent variable, including units, in your experiment. D. Identify the dependent variable, including units, in your experiment. E. Identify at least one control treatment and explain its specific role in the experiment.Answer this Hardy-Weinberg Equilebrium ProblemAbout 9 percent of Caucasian males are color-blind andcannot distinguish red-colored from green-coloredobjects.a.

- Which of the following statements accurately describes some of the allele and chromosome (haplotype) frequencies? B O a. fA: 0.4, fAB: 0.32 O b.fg: 0.2, fAb: 0.12 O c. fA: 0.6, faB: 0.48 O d. fB: 0.8, fab: 0.8 ABAn allele of the G6PD gene acts in a recessive manner to cause sensitivity to fava beans, resulting in ahemolytic reaction (lysis of red blood cells) afteringestion of the beans. The same allele also confersdominant resistance to malaria. The heterozygote hasan advantage in a region where malaria is prevalent.Will the equilibrium frequency (qe) be the same foran African and a North American country? Whatfactors affect qe?experiments followed from mendals cross and developed from the conclusions he made as a result of the first monohybrid cross. State what ratio of offspring he would have predicted from these crosses. b Calculate the actual ratios obtained in each of these crosses. c Suggest what chance events may influence the actual ratios of offspring obtained in breeding experiments like these. (We will return to this issue at a later point. For example, the statistical test known as the chi-squared test can be applied to the results of genetic crosses to test whether the actual results are close enough to the predicted results to be significant.)
