2. An investigator is following segregation of two different traits in a plant model system, Arabidopsis thaliania. The two traits are plant height (H (wild-type); h (short)) and flowering (F (wild-type); f (extra flowers). This investigator first crosses a true-breeding short plant with a true breeding plant with extra flowers. The F1 progeny were all wild type. To then test whether the two traits are caused by two unlinked genes, he crossed two F1 plants. The results are shown in the table below: Phenotype Wild type (normal height and flowering) Normal height, extra flowers Short, normal flowering Short and extra flowers # progeny 245 48 77 9 Analyze the results using the chi-square test to determine whether the data fit the hypothesis that plan height and flowering are determined by two independently segregating genes. Your work supporting your conclusion must be shown for full credit.
