AP Bio: Non Mendelian Genetics Lesson

A student crosses a pure-breeding line of red-flowered poinsettias with a pure-breeding line of white-flowered poinsettias. The student observes that all the plants in the F1 generation have pink flowers. The student then crosses the F1 plants with one another and records the observations about the plants in the F2 generation. The student will use the F2 data to perform a chi-square goodness of fit test for a model of incomplete dominance. The student's chi square is presented in Table 1.

If the χ² _critical value = 5.99 and the

χ² _calculated value = 7.35, what is the conclusion

The student observes that all the plants in the F1 generation have pink flowers. The student then crosses the F1 plants with one another and records observations about the plants in the F2 generation. The student will use the F2 data to perform a chi-square goodness-of-fit test for a model of incomplete dominance. The setup for the student’s chi-square goodness-of-fit test is presented in Table 1.
