Transition bias

[Jonathan F Wendel]

A familiar observation in many DNA sequence data sets is
transition/transversion bias.  I am wondering, though, whether there is
any information on biases WITHIN transitions.  Specifically, are there data
on AG versus CT transition frequencies in either plants, fungi, or animal
nuclear or organellar genomes? I have some interesting data and I'm
attempting to ascertain whether my observation is novel or commonplace (and
that I am simply naive!).

Please respond to me by email.  I will synthesize the remarks I receive and
post them.  Thanks.
