A particular article reported the accompanying data on phenotypes resulting from crossing tall cut-leaf tomatoes with dwarf potato-leaf tomatoes. There are four possible phenotypes: (1) tall cut-leaf, (2) tall potato-leaf, (3) dwarf cut-leaf, and (4) dwarf potato-leaf. Mendel's laws of inheritance imply that ?1 = 9/16, ?2 = 3/16, ?3 = 3/16, and ?4 = 1/16. Are the data from this experiment consistent with Mendel's laws? Use a 0.01 significance level. (Use 2 decimal places.)

A crop researcher investigated the phenotypes that resulted from crossing two different types of cucumber plants. There are 4 possible resulting phenotypes (numbered 1, 2, 3, 4 in the data table below). Mendel's laws of genetic inheritance ('the model') suggest that the proportions should be 9/16, 3/16, 3/16 and 1/16 for phenotypes 1, 2, 3, 4 respectively.
The classification of a sample of 1400 observations is given below together with the proportions suggested by Mendel's laws of inheritance (the model)

- The epidemiological, clinical, and bacteriological aspects of shigellosis were studied in a population of hospitalized children in northern Israel. Shigellosis invades epithelial cells of the colon and causes inflammation a severe cases of diarrhea and dysentery. Below is a table that lists the frequencies of two different species of Shigella: S. sonnei and S. Flexneri between hospitalized and non-hospitalized Jews and Arabs. a) Combine hospitalized and non-hospitalized children, what is the overall prevalence of: sonnei among Jewish children: ____________________________ sonnei among Arab children: ____________________________ Flexneri among Jewish children: ____________________________ Flexneri among Arab children: ____________________________ b) Calculate a 95% confidence interval for the population difference in prevalence of S.

To account for this, the researcher grows two seedlings from each of the 10 tomato varieties. One seedling of each variety gets side-dressed nitrogen and the other receives no side-dressing. In this study, the observation for each variety in a sample is matched with the observation for the same variety in the other sample. Suppose the researcher intends to compare the two groups of tomato varieties. What is the unit of interest and variable of interest? What is the appropriate test procedure in comparing the two groups (with and without side dressing)?arrow_forwardBiologists wish to mate pairs of fruit flies having genetic makeup RrCc, indicating that each has one dominant gene (R) and one recessive gene (r) for eye color, along with one dominant (C) and one recessive (c) gene for wing type. Each offspring will receive one gene for each of the two traits from each parent, so the biologists predict that the following phenotypes should occur in a ratio of 9:3:3:1. Phenotype Frequency Red eyes and Red eyes and straight wings curly wings 99 42 White eyes and straight wings 49 White eyes and curly wings 10 Use a chi-square goodness-of-fit test to compute a test statistic and P-value. At the a = 0.05 significance level, what can be concluded about the proposed genetic model? Because the P-value of 0.1029 > 0.05, we cannot reject the null hypothesis. We do not have convincing evidence that the distribution of eye color and wing shape is different from what the biologists predict. Because the P-value of 0.5177 > 0.05, we cannot reject the null…arrow_forward

There are several possible mutations of different degrees of importance but the disease expresses itself only when at least 2 arepresent in any one individual.
