Nope. Most will be probably be around 10% carrot tail. Others may not be carrot tail at all and you may also get some with 10+% carrottail. Let me give you a comparison. Your mom has lots of freckles, and so does your dad. They both have lots of kids. Now most of those kids will have lots of freckles, right? But a few may have less or no freckles, and a few may have even more freckles. Make sense?
