SUMMARY
Gene imprinting is a biological phenomenon where certain genes are expressed exclusively from the allele inherited from one parent, typically influenced by the parent's sex. This mechanism provides advantages such as enhanced adaptability to environmental changes and protection against invasive trophoblasts. Current theories suggest that gene imprinting may also play a role in sibling interactions, where natural selection operates differently on maternal and paternal genes, thereby influencing genetic expression and evolutionary outcomes.
