This is а multipаrt questiоn bаsed оn using a chi-square analysis tо test hypotheses about genetics crosses, practiced as part of the Genetics Lab. Be sure to answer all Parts A-D. Answer in the space at the bottom. In a monohybrid cross for flower color (F1 cross: CRCW x CRCW), which displays incomplete dominance, plants bearing the following flower colors with their frequencies were observed in the F2 generation: Red Flowers (CRCR) = 31 Pink Flowers (CRCW) = 62 White Flowers (CWCW) = 25 The research question being asked here is whether the observed frequencies above differ from expected frequencies (of course, if F1 generation alleles follow the law of segregation and pollination is random.) (A.) (2 points) Assuming the law of segregation was followed and that pollination was random, write a null hypothesis for this experiment. In other words, fertilization causes alleles to combine in a random fashion, and a Punnett square can be used to determine expected frequencies. (B.) (2 points) Write the alternate hypothesis for this experiment. Perform the appropriate statistical test (chi-square test) to determine which hypothesis about the frequencies should be rejected. (You may use the table below to help with your calculations. For convenience the observed frequencies have already been listed in the table. Answers will be reported in the format indicated in Part C below.) (C.) (5 points) Report the results of the analysis in the spaces below indicating the X2-value, the number of degrees of freedom (d.f.), and if the probability (p) is , or = to 0.05. Use the critical chi-square values in the table below to determine if the probability is above or below the significance level (alpha = 0.05). Use the following format for this answer, typing the correct values or sign instead of the blanks: “C. X2 = _______, d.f. = _____, p ____ 0.05” (D.) (1 point) Based on your chi-square test above, indicate if your null hypothesis is supported or rejected in favor of the alternate hypothesis. Before responding to each part in the space below, write the letter of the part you are answering (e.g., A. [Answer response to the question A]). If you do not know the answer to a question, write the letter, then hit enter to move to the next line, and type the letter of the next question to answer.
