The one shown is on a sucker so it is already unbalanced.

It happens a bit more than one would suspect.

It usually grows an ugly, small, mostly undeveloped cob with spotty grain fill.

Like noted above, they tend to show up on tiller ears.

The wild ancestors of corn (ie teosinte) have their male + female parts all together (much like many grains). Domestication of crops occasionally shows some signs of their genetic ancestors.

Thanks folks! Interesting stuff nc-crn...... i see a lot of this in new strains of super hot peppers in the form of pod variation.........
