Be sure to answer all of the questions below in the single text box provided. From the dihybrid cross above, suppose that a researcher wanted to determine whether smurf color and smurf breath are independently inherited (assort independently) or are genetically linked. a) How would the researcher state his/her hypothesis, as it relates to Mendel’s law and observed vs. expected numbers, before conducting a Chi-square analysis? The null (Ho) would state that: The alternative (Ha) would state that: b) Suppose that after counting the number of observed offspring, the researcher calculated a Chi-square value of 11.35. Using the table below, what would the p-value for this analysis be? (Hint: the df, or degrees of freedom here, would be 3.) c) Based on the p-value you got from b), are the traits inherited independently (do they follow Mendel’s Law of Independent Assortment), or are they linked? (Remember: the “cutoff” for statistical significance is a p-value of 0.05)
