Do we have corn in our DNA?
The basics: Corn has 32,000 genes packed into 10 chromosomes (humans have 20,000 genes spread among 23 chromosomes). About 85 percent of the corn DNA has these segments that are repeated; that compares to only about 45 percent of human’s DNA. In some shape or form, you’ll likely be eating corn tomorrow (and everyday).
