"Mouse Parenting: The Influence of Genetic Imprints"
Researchers have discovered a link between imprinted genes and parenting behaviors in mice. Imprinted genes, which allow only one parent's copy to be active, were found to influence parental care. The gene Magel2 was identified as a significant imprinted gene affecting parenting behavior, with mice lacking an active form of Magel2 being neglectful parents. The findings suggest that imprinted genes may have evolved to synchronize parenting activities between mother and offspring.
