Can a DNA Test Predict Your Success in Love?

Feb 14, 2013 | Science and Technology

This Valentine’s week at DDC, we’re taking time out from the usual to discuss the topic of DNA compatibility. This topic was brought to national attention a few years ago by a landmark “sweaty t-shirt study.
In the experiment, men were asked to wear the same T-shirt for two nights. They then returned the shirts to the scientists, who packaged each shirt in a box equipped with a “smelling hole.” In turn, women were asked to sniff the shirts and rate the odor in terms of intensity, pleasantness, and sexiness. Significantly, the women were attracted to the odor of males whose genes for an immune system component, the major histocompatibility complex (MHC), were vastly different from their own.

This result seems to indicate that opposites do attract, on a genetic level. Some suggest that we are wired to do so in order to ensure a good genetic variation in the next generation–and thus improved chances of survival. A similar study on married couples found that the couples were less likely to share similar genes for the human leukocyte antigens (HLA). Couples who do share HLA variants were found to have increased associations with recurring spontaneous abortions, reduced body mass in babies, and longer intervals between successive births.

Does this mean that prospective mates should test their DNA to see if they are compatible, in an effort to avoid failed relationships? Not just yet. Scientists are quick to point out that we are a product of both our genetics and experiences (nature and nurture). In fact, one study shows that “social factors trump genetic forces in forging friendships.”

For now, here at DDC, we’re sticking with what’s clear and determined: a child’s DNA is a combination of alleles inherited from the mother and father. And that’s the basis for all our family relationship DNA tests.

How DNA Testing Has Changed

1920s - Blood Typing In the early 1900s, scientists identified 4 different blood types in humans - A, AB, B, and O - based on the presence of certain proteins called antigens in the blood. This blood typing system, called the ABO system, provided doctors with crucial...

How Long Does Immigration Testing Take?

DNA testing is often required in immigration cases where a U.S. citizen is sponsoring the immigration of a relative and needs to prove to the U. S. Customs and Immigration Service (USCIS) or U.S. embassy or consulate that the person seeking to immigrate to the U.S. is...

What Do I Do with the Results of the DNA Test?

The results of your ancestral DNA tests can be used in a few different ways. Of course, the test will verify biological relationships you uncovered in your research. After DNA testing you will know that you are (or are not), in fact, biologically related to the family...
