High rate of transition to transversion ??

Hello evolusionnists,

I have many non-coding sequences. I have compared each one to the others and 
between the results that I've got, there is the ratio of the transitions to 
the transvertions. This number was almost similar between the most pairs of
sequences but between few pairs this ratio was so high (X3 to X11).
In this last pairs the sequences was coming from isolates with a close  
relationship (close geographic origine).
My question is why and how we can explane this event ? does it mean some-
thing ?

I thank you very much for your help
