Why Genes Of One Parent Are Expressed Over Genes Of The Other: New Ideas In Genomic Imprinting

How we come to express the genes of one parent over the other is now better understood and it doesn't seem to have originated in association with sex chromosomes. New research has shed light on the evolution of genomic imprinting, in which specific genes on chromosomes that have been inherited from one parent are expressed in an organism, while the same genes on the chromosome inherited from the...
