Strawberry Bed After Selection
This is the strawberry bed shown earlier, after selection has been made according to the standards shown previously, and the unsuitable plants weeded out. The fruit that grows on the comparatively few selected vines will be carefully preserved to carry forward the experiment. The blossoms may be hybridized with other varieties to secure variation, or it may be necessary only to select the best among the seedlings, without further experiments in cross-fertilizing. This typical experiment illustrates the survival of the fittest under conditions of artificial selection.
