Question

In corn, a pair of genes determines leaf shape and another pair determines pollen shape. A ragged-leafed plant with round-pollen was crossed to a ragged-leaf plant with angular pollen, and the resultant progeny were classified as follows:

                                                186 ragged-leaf round-pollen

                                                174 ragged-leaf angular pollen

                                                57 smooth-leaf round pollen

                                                63 smooth-leaf angular-pollen

 

provide your hypothesis of the genotypes for the two parents.

According to your hypothesis, what numbers would you have expected for each of the four classes of progeny? Follow the format of the number with the phenotypes in the question above.

Test your hypothesis statistically using the chi-square method and indicate whether you accept or reject your hypothesis. Show your solutions.
