In the new study, researchers gathered a detailed history of sexual behavior and relationships from 181 young adults. They also collected DNA samples from the volunteers' cheeks and analyzed the samples for the presence of the thrill-seeking version of DRD4, buy vibramycin without prescription.
"What we found was that individuals with a certain variant of the DRD4 gene were more likely to have a history of uncommitted sex, canadian vibramycin, Cheap vibramycin in usa, including one-night stands and acts of infidelity," study researcher Justin Garcia, vibramycin sale, Cheap vibramycin, a postdoctoral fellow at Binghamton University, State University of New York, lowest price for vibramycin, Vibramycin pills, said in a statement.

"The study doesn't let transgressors off the hook," said Garcia. "These relationships are associative, which means that not everyone with this genotype will have one-night stands or commit infidelity.

The study merely suggests that a much higher proportion of those with this genetic type are likely to engage in these behaviors."
This raises some interesting questions. If alcohol and gambling are defined addictions, does this DNA correlation suggest that hooking-up should also be defined as an addiction? And if a predilection for infidelity can be screened by a DNA test, could a DNA test become a standard for the smart bride and groom's pre-marital tests.
