A colleage and I have demonstrated an imprinting-like phenomenon in a
zebrafish transgene (parent-of-origin changes in DNA methylation).  While
not demonstrating mono-allelic expression in these studies, fish appear to
have a mechanism operating similar to imprinting in mammals ... it likely
is most similar to the pseudo-imprinting of the gene brachyury in the
mouse T mutants
