Any signs to doubt they are pure T.radix

I have had a few people say that my garters are not pure T.radix and look like inter-grades. What does everyone think, I'll start with the male here are some photos. If there are any defining features you want photographing please tell me. Pics of females can be found on my other thread http://www.thamnophis.com/forum/general-talk/9565-photos-my-plains-garters.html until i get some more.

Sweet natural looking T.radix.
Did this person/s say why they thought it was a hybrid?
