In fruit flies, purple eyes and ebony body are traits that display autosomal recessive patterns of inheritance. In a
genetics experiment, students cross wild-type flies with flies that have purple eyes and ebony bodies. The students
observe that all the flies in theF1 generation have normal eyes and a normal body color. The students then allow the
F1 flies to mate and produce an F2generation. The students record observations about the flies in the
F2 generation and use the data to perform a chi-square goodness-of-fit test for a model of independent assortment.
The setup for the students' chi-square goodness-of-fit test is presented in Table 1.

step of the chi-square goodness-of-fit test?
a. The calculated chi-square value is 2.11, and the critical value is 7.82.
b. The calculated chi-square value is 2.11, and the critical value is 11.35.
C. The calculated chi-square value is 10.48, and the critical value is 7.82.
d. The calculated chi-square value is 10.48, and the critical value is 11.35.
