A conflict may emerge between maternal and paternal genes over how the members of the group should act.

To imply that fetuses distinguish between maternal and paternal genes is without scientific basis.

Michael, a neuroradiologist, and Paul, a lawyer, are both married with children and have inherited the paternal fiddling gene.

The boy was quiet, a paternal gene passed on.

The paternal gene complements are marked on each one, so you should have no trouble telling who they belong to.

In some cases, either the maternal or paternal gene is silenced, or prevented from being translated into protein.

The investigators found that a class of compounds-topoisomerase inhibitors-could unsilence the paternal gene.

This intragenomic conflict between maternal and paternal genes can lead to pseudo-arrhenotoky arising.

A homozygous mutation means that there was an identical mutation on both the maternal and paternal genes.

It is passed down through generations, unmixed with paternal genes, and so is easily traced.
