Question
In garden peas, plants with purple flowers and white flowers are found. When peas of a true breeding purple strain were crossed with white flowered peas, the F1 all had purple flowers, F1 plants were allowed to self-fertilize, and in the F2, 550 purple flowered and 250 white flowered plants appeared. (A) Diagram this cross and give parental phenotypes, genotypes, as well as F1 and F2 genotypes and phenotypes. (B) Use the chi-squared test to determine if the F2 progeny obtained fit the predicted ratio for a hybrid cross.
