Xu Wang, Doug Antczak, Andy Clark and colleagues report the analysis of RNA-sequencing of trophoblast tissue from horse, donkey and their reciprocal F1 hybrids, the mule and hinny. Results show a remarkably clear pattern of genomic imprinting in the placenta, with a marked preponderance of paternal allelic expression of imprinted genes. Their paper was published in the June 10 2013 issue of the Proceedings of the National Academy of Sciences.
