Web Desk: Do you know, the secret of a happy married life? A recent scientific study may give you the answer.
According to a new study, Genes may impact the quality of marriage by determining how partners provide and receive support from each other, report The Week.
The study, published in the Journal of Family Psychology, evaluated whether different genotypes or possible genetic combinations of the Oxytocin Receptor gene (OXTR) influenced how spouses support one another, which is a key determinant of overall marital quality.
OXTR was targeted because it is related to the regulation and release of oxytocin, which is a hormone associated with feeling love and attachment.
Oxytocin also appears to be relevant to social cognition and a wide range of social behaviour.
“Prior research has hinted that marital quality is, at least partially, impacted by genetic factors, and that oxytocin may be relevant to social support—a critical aspect of intimate partnerships,” said Richard Mattson, Associate Professor at Binghamton University in the US.
“However, we are the first to provide evidence that variation on specific genes related to oxytocin functioning impact overall marital quality, in part, because they are relevant to how partners provide and receive support from each other,” Mattson said.
The findings highlight that particular genes may impact marital quality by influencing important relational processes, but that context shapes when particular genotypes are more or less beneficial to the marriage.
“We found that variation at two particular locations on OXTR impacted the observed behaviours of both husbands and wives, and that differences in behaviour across couples had small but cumulative effects on overall evaluations of support, and thus marital quality in general,” said Mattson.
“However, what emerged as most relevant to overall marital quality for both partners was genotypic variation among husbands at a specific location on OXTR.
“Husbands with a particular genotype, which other researchers associated with signs of social deficits, were less satisfied with the support they were provided,” he said.
“Genes matter when it comes to the quality of marriage, because genes are relevant to who we are as individuals, and characteristics of the individual can impact the marriage,” said Mattson.
“Our findings were the first to describe a set of genetic and behavioral mechanisms for one possible route of the genetic influence on marriage. In addition, we added to the increasing awareness that the expression of genotypic variation differs greatly depending on context,” he said.
