Genomic imprinting means that specific genes inherited from the mother or father are active, whilst the gene inherited from the other parent is inactive. This preferential expression of one allele is ...

For more than 20 years, DNA methylation has been the only known mechanism for regulating mammalian germline imprinting. Now, researchers at Harvard Medical School and Boston Children’s Hospital have ...
