The "navel" of the navel orange is caused by a genetic mutation, and the navel of the navel orange is another small navel orange.
Originally, navel oranges originated from dendritic changes, that is, branches that were mutated after mutations in orange buds that were different from the genetic material of other parts of the plant.
There is no scientific basis for determining the male and female of an orange based on the size of the orange navel and whether it is dented or not.

In fact, the "fruit divider" is only a metaphor for the shape of the fruit, which belongs to an empirical subjective judgment. Scientific experiments have confirmed that the distinction between "male and female" of the fruit is only a folk legend, and there is no distinction between male and female after the fruit is ripe. In biology, there is no such thing as a male or female to fruit. The taste of the fruit is closely related to the time and intensity of the sunshine, the soil where it grows, the age of the fruit trees, the origin and variety of the fruit.
Fruit color is the key indicator to measure the quality and flavor of the fruit, and the color change of the fruit in the harvest link is the most intuitive embodiment of judging the ripeness and nutritional quality of the fruit. Consumers can choose oranges according to the mature color of different varieties of oranges.
