You do NOT need to submit graphs or data tables. Give the terminal regression line equation and R or R² value: Give the x axis (name and units, if any) of the terminal line: Give the y axis (name and units, if any) of the terminal line: Give the residual regression line equation and R or R² value: Give the x axis (name and units, if any) of the residual line: Give the y axis (name and units, if any) of the residual line:

3. In the tomato, red fruit (O+) is dominant over orange fruit (0), and yellow flowers (W+) are dominant over white flowers (w). A cross was made between true-breeding plants with red fruit and yellow flowers, and plants with orange fruit and white flowers. The F₁ plants were then crossed to plants with orange fruit and white flowers, which produced the following results: a. b. 333 red fruit, yellow flowers 64 red fruit, white flowers 58 orange fruit, yellow flowers 350 orange fruit, white flowers Conduct a chi-square analysis to demonstrate that these two genes DO NOT assort independently. Make sure to interpret the P value obtained from your chi-square test. Calculate and provide the map distance (in map units) between the two genes.
