In the case of hybridized seeds, the two parent plants are grown together in a controlled environment, such as a greenhouse, to ensure that the resulting plants have the desired characteristics of both parents. For example, if one parent is a tomato plant and the other is an apple tree, then the result will be a hybrid tomato and an inbred apple.
