Family Genetics May Play a Role in Divorce Likelihood

genetics, Wheaton family law attorneysRelationship and social science experts have known for generations that children of divorced parents are more likely to get divorced later in life than children whose parents stayed together are. Of course, knowing that something is more likely to happen is not the same as knowing why that thing is more likely to happen, especially when it comes to children and families.

Noted scientists have long gone back and forth on the issue of “nature vs. nurture” in many areas of study. The debate boils down to two simple questions with quite complex answers. How much of a person’s behavior is determined by the environment in which he or she was raised, and how much is determined by his or her genetics and evolutionary instincts? A recent study suggests that divorce, of all things, may be linked to a person’s genetics more than we ever really thought possible.

Putting Ideas to the Test

Last fall, a team of researchers from Virginia Commonwealth University and Sweden’s Lund University conducted a large-scale study that is considered to be one of the first of its kind. The team examined the marriages and family histories of nearly 20,000 individuals who had been adopted as children and raised by someone other than their biological parents. By looking solely at adopted men and women, the study essentially created a divide between biological and environmental influences.

The researchers found that when the adopted adult children were 20 percent more likely to get divorced if their biological parents got divorced, regardless of any contact between the adopted child and the biological parents. When their adoptive parents got divorced, the adult children were no more and no less likely to get divorced themselves.

The team also looked at situations involving biological and adoptive siblings who were raised in the same households. The results again showed that subjects tended to show marital and divorce patterns similar to their biological brothers and sisters, not their adopted siblings, despite being raised in the same environment.

Breaking New Ground

The study’s authors say that their findings are notable and that they diverge dramatically from most of the information currently available about divorce and family relationships. “Nearly all the prior literature emphasized that divorce was transmitted across generations psychologically,” said one of the researchers. “Our results contradict that, suggesting that genetic factors are more important.” The team hopes that recognizing the genetic components of divorce will help therapists develop more effective strategies for assisting couples in crisis.
