If there was a gene for good parenting, would you want to be tested? Would you want to test your parents?
Dutch researchers published a study that suggests our genes may determine our parenting behavior. They found a correlation between nurturing behaviors and particular genetic variations. The finding highlights the role of serotonin and oxytocin in healthy human relationships.
Oxytocin is a hormone that’s also a neurotransmitter in the brain, so it’s used by neurons to communicate with each other. Oxytocin has long been recognized as a crucial hormone for mammalian bonding.
The study looked at 159 middle class mothers with 2-year-old sons, and they found that women who have a variant of a gene which encodes a part of the oxytocin system — this variant is known to make the oxytocin system a little less effective, less efficient in the brain — seemed to be less sensitive to their child on a variety of measures, like how quickly they respond to crying, how often they kiss their child.
