Why is there in the tops of the corn?

Corn plants bloom male flowers on the tops and flowering flowers in the middle of the body. Male pollen drops, female flowers pollinate and produce seeds. That is the reason why corn often appears in the middle of the body. However, sometimes you will meet corn plants with corn on the tops.

Corn (corn) belongs to the rice family, originating from the subtropical highlands of Central and South America, now being moved around the world with many different varieties.

At the beginning, corn is a species of stamen (male) and stamen (female) in the same flower. After, through natural selection and care of humans, corn gradually evolved: a tendency in flowers on the tops to degenerate, stamen in the flower in the middle of the tree also degenerated. The reproductive organs that are degenerate are still traces, but in normal conditions there is no sexual development. Only when certain conditions are met, such as too many sunny days or unusual male flowers, corn plants are corn on the tops. That is the same phenomenon again.
