Although most people would say they're exactly identical, recent results from a home DNA test revealed they're actually not.
According to Life Buzz, Erica, Jaclyn, and Nicole Dahm were impossible to differentiate before they developed their own personality traits, but a recent DNA test says otherwise.
During an episode of The Doctors, the triplets sat and discussed the results of an at-home DNA test they decided to take together.
Inside Edition's investigative reporter Lisa Guerrero conducted a test in which they discovered that the triplets have different ancestry data.
“Nicole, you’re 18 percent British and Irish. Erica, you’re 15 percent British and Irish. But Jaclyn, you’re almost 19 percent British and Irish,” Guerrero told the triplets on the set of The Doctors.
Healthy Way reached 23andMe, the service that interpreted the genetic test for the Dahm sisters, discovering the results were misinterpreted.
A spokesperson explained that it's not that they have different ancestries, claiming that there are "confidence levels" assigned to each variable, and while reports can change depending on the user’s selected confidence level, the data would have been largely the same.
"If we say that a section of DNA is most likely Japanese or Chinese or Korean at one of our higher confidence thresholds, we stand behind it. If we weren’t sure that we could make the distinction, we’d go up a level and say that that DNA reflected ‘East Asian’ ancestry. The information would not be incorrect, simply less specific," they said.
Since they were three babies, the triplets' parents had to resort to desperate measures just to differentiate their daughters, as they marked them in the buttocks.
The first one, Nicole, was marked with a dot in her behind. Erica received two dots due to being the second, and Jaclyn, the last one to be born, was the one who wasn't marked.
As they were growing, they became best friends and didn't spend much time apart, and while for many this could be considered annoying, they love to be perceived as a group.
At the age of 16, the triplets entered a Teen Magazine contest called The Great Model Search. Although there was good competition, the girls won and were featured on the magazine's cover.
As modeling jobs tend to be an unstable income, they decided to have a backup plan and went to the University of Minnesota, where they majored in nursing in order to work together.
