Even though we all have two copies of every gene, one from Mom and one from Dad, there is
a small subset of genes (less than 2 %) that is only ever expressed from one copy: and the choice of that copy is dependent on the parent from which it was inherited.
Notably, the majority of the most highly conserved non-coding sequences in mammalian genomes are clustered near
a small subset of genes with important roles in development.
