…on average, how many rows of kernels are on an ear of corn?
The first ears of corn were short, only a few inches long and originated in Mexico. Fast forward through centuries of breeding and we have the modern bigger, fuller ears of corn. On average, a modern ear of corn has 16 rows of kernels. Although the actual number of rows can vary, the number will always be even. The number of kernels on an ear can vary from 500 to 1,200. Genetics determine the number of ears that a single corn plant will grow.
