| Wheat has a inflorescence structure called a | spike |
| Basic unit of heredity is the | gene |
| Types and frequencies of gametes produced by an individual with genotype Aa would be | 1/2 A and 1/2 a |
| A banded application of a pesticide or fertilizer | is applied between rows or over rows |

| Legume flower has | petal, keel, and wings |
| General categories of pesticides include | Rodenticides, fungicides, herbicides, adn insecticides |
| Correct order for variety development is | Breeder seed - Foundation seed - registered seed - certified seed |
| The basis for determining the value of grain involves | cleanliness, purity, and moisture |
