In Iowa, a company called Team Corn works to ensure that fields of seed corn outcross so that hybrid vigor can be maintained. They do this by removing the staminate (that is, pollen-producing) flowers from the corn plants. In an attempt to put Team Corn out of business, you would like to develop genetically engineered corn plants that a. contain Z genes to prevent germination of pollen on the stigmatic surface. b. contain S genes to stop pollen tube growth during selffertilization. c. express B-type homeotic genes throughout developing flowers. d. express A-type homeotic genes throughout developing flowers.
