Green grape with a bunch or red grapes? Got answers, thanks. :)

It just seems kind of wierd to me. I found a green grape (it looked a little rotted though) in my bunch of red grapes. It was attached to the vine still so it was supposed to be with this bunch of grapes...
They aren't organic or anything. Just the 99 cents a pound red grapes that Price Chopper had on sale.
Is it normal to have a green grape in the bunch or should I worry? :/

Just a mutation. I wouldn't worry, but if it looks bad, don't eat it.

well..it is either more or less ripe. I love olives. I just recently discovered that all olives are black...green olives are just not ripe. I love salty green olives, and can do without black olives. Maybe the same thing?
