Fresh Summer Corn 10 Ways Elote, Corn Gratin, Corn Chowder & More!
video description
Each kernel is a separate entity, originally from a tiny flower produced by the mother. As such mom can contribute different genetics to each flower. Also as they are all individual flowers, they can all be fertilized by different fathers pollen, which will obviously vary somewhat.
After those common genetics are factored, there is also stuff going on inside the DNA. Transposons, aka 'jumping genes' can unattach from on part of the DNA strand and reattach somewhere else, which either changes the gene altogether, or interferes with some of its normal abilities. In this case (as in my mates PhD thesis, Dr Caitlin Coberly) the interference is with color. DNA chugs along, gets to the instructions for its base color and runs into a variation.
If you are interested, the Nobel Laureate who discovered this is Barbara McClintock, and it is on this that all genetic engineering is based.
