In a series of three experiments, M. G. Addo sought to use chi-square test to
determine the goodness of fit at 5% for each of his results below. Carry out the
calculations and determine whether the results obtained in each case are
consistent with the 3:1 or 1:1:1:1 ratio he predicted in his hypothesis. Comment
on your results.

Hotchkiss and Marmur noted that the percentage of cotransformation was higher than would be expected on a random basis. For example, the results show that 2.6% of the cells were transformed into M and 4% were transformed into S. If the M and S traits were inherited independently, the expected probability of cotransformation of M and S (M S) would be 0.026× 0.04 = 0.001, or 0.1%. However, they observed 0.41% M S cotransformants, four times more than they expected. What accounts for the relatively high frequency of cotransformation of the traits they observed?
QTL mapping and GWA (association) mapping are two different methods used to identify genes that affect complex traits. For each of the following statements, choosewhether it applies to QTL mapping, association mapping, or both.whether it applies to QTL mapping, association mapping, or both.

- What is probability, and how is it applied in genetic analysis?arrow_forwardI have seen that this was answered as C, Why is the answer C, how is that not evidence of it being genetic? Shouldnt it be none of the above? Question: Of the following, which supports the idea that alcoholism has no genetic or a low genetic component? a) Some strains of mice select alcohol over water 75% of the time, whereas others shun alcohol. b) The concordance value is 55% for MZ twins and 28% for DZ twins. c) Biological sons of alcoholic men who have been adopted have a rate of alcoholism more like that of their adoptive fathers. d) There is a 20% to 25% risk of alcoholism in the sons of alcoholic men. e) None of these.arrow_forwardSickle cell anemia is a genetic disease most common in those of African ancestry that results from the mutation of a single basepair. This mutation results in a change to the hemoglobin protein. In this experiment, “S” will represent the normal allele and “s” thesickle allele. They are codominant alleles. Therefore, SS is normal, Ss is not fatal but mildly symptomatic, and ss is debilitating,painful, and often fatal. After hundreds or even thousands of generations, both alleles are still common in those of African ancestry. How would you explain this?arrow_forward
- A genetic engineer was attempting to cross a tiger and a cheetah. She predicted a phenotypic outcome of the traits she was observing to be in the following ratio: 4 stripes only: 3 spots only: 9 both stripes and spots. When the cross was performed and she counted the individuals she found 50 with stripes only, 41 with spots only and 85 with both. What is the computed chi-square value?

- In assessing data that fell into two phenotypic classes, a geneticist observed values of 250:150. She decided to perform a x2 analysis by using the following two different null hypotheses: (a) the data fit a 3:1 ratio, and (b) the data fit a 1:1 ratio. Calculate the x2 values for each hypothesis. What can be concluded about each hypothesis?arrow_forwardUsing the numbers provided in the attached image for the observed progeny counted for the testcross shown in the question above, perform a Chi-square analysis to determine whether you are correct as to the genotype of the unknown individual. Be sure to include a properly phrased hypothesis, the degrees of freedom, a complete Chi-square table, the Chi-square value, p-value range, and your determination of whether your hypothesis was correct.arrow_forwardThe following are F2 results of two Mendel mono hybrid crosses.
