This picture tells a pollination story that every gardener should be aware of. The light-colored, undeveloped fruit at the right was a female blossom that opened when there were no male blossoms open. The blossom was not pollinated and the fruit failed to develop. The developing fruit on the left was a female blossom that opened when male blossoms were also open and there were bees to complete the cross-pollination. Result: one fine Zucchini squash in the making.
