Q about recombination

[kuiken at amc.uva.nl]

Hello,

Does anyone know of a paper describing genes from a viral genome 
'behaving' more independently (e.g. moving to different locations
in a phylogenetic tree) the further apart they are in the 
genome, due to recombination? I've been told that this has been
described by Temin, but I cannot find the paper. Any other ref
showing this would also be very welcome. Thanks a lot.
