Imprinted gene example
Witryna3 mar 2016 · Genomic imprinting is a fairly rare phenomenon in humans, most genes are not imprinted, and most of studies are done in mice or plants, so we have a lot to do in this field. Although we do not yet know the precise mechanisms underlying epigenetic gene regulation in the pathogenesis of several diseases, there are finding that the … WitrynaAn example of imprinting is the differences noted between the mule and the hinny. The mule is the cross between a maternal horse and a paternal donkey. It is much larger than the hinny, which is a cross between a maternal mule and a paternal horse.
