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.

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

Its exact cause is unknown, but present research points toward a genetic component, possibly following maternal genes.

The maternal genes could somehow make possible that recognition.

For her age, she was an unusually determined and purposeful girl, quite full of the maternal genes in that respect.

Genomic imprinting is surmised to have arisen due to the conflicting interests of maternal and paternal genes within a pregnancy.

The patterning from the maternal genes work to influence the expression of the segmentation genes.

These genes are influenced by not only the maternal genes, but also by epistatic interactions between the other gap genes.
