Hung over? Blame your family for that.

Researchers surveyed more than 2,000 pairs of identical twins who consume alcohol, and they found similarities between twins' responses, according to IOL SciTech.

About 4,000 middle-aged people from the Australian Twin Registry reported their experiences with alcohol and hangovers during a telephone survey, according to Live Science. Twins from the same family tended to give similar responses.

Researchers also concluded that those with the "hangover gene" (those who get hungover) were typically those who drank more frequently, which may be a key to unlocking an understanding of addiction.

"We have demonstrated that susceptibility to hangovers has a genetic underpinning. This may be another clue to the genetics of alcoholism," study leader Wendy Slutske, a psychology professor at the University of Missouri-Columbia, told Live Science.

The genes involved may be those responsible for inflammatory processes, according to IOL SciTech.
