High Performance Computing Research show your mate likely has similar height, weight, and education profile
Do you already have a Valentine or still looking for love? New research using high-performance computing (HPC) shows that you are most likely married to or will marry someone who is the same height and has the same body weight and education as you – and it’s because of your genes.
Scientists at the University of Queensland in Brisbane, Australia studied more than 24,000 opposite-sex married couples of European ancestry, analyzing the genetic markers for traits such as height and body mass index (BMI), according to a recent ScienceNode story. Their study uncovered that people have a genetic disposition to find marriage partners that are very much like themselves.
They discovered a strong statistical correlation between people’s genetic markers for height and the actual height of their partners, the story said. They also found a significant but weaker correlation between people’s genetic markers for BMI and the actual BMI of their partners. That suggests that people have actively chosen partners with genes that are similar to their own, the story said.
Furthermore, the researchers analyzed 7,780 couples in a U.K. database and sought out genetic markers that have previously been linked to the amount of education people have. In doing so, they found a high correlation of married couples with the same education, according to a story in the weekly science journal Science.
While it doesn’t mean people pick their partners based on actual years of education, it implies that they choose them because they have similar interests, which are associated with levels of education, the Science story said.
University of Queensland’s Matthew Robinson, who led the study, used an HPC system to analyze 1.2 million genetic markers in 48,000 people. They also relied on an HPC system to conduct a simulation study to test the accuracy of their theory and determine whether their analyses would provide reliable results, the ScienceNode story said.
The study, published in the journal Nature Human Behaviour, only examined people of European ancestry in the United States and Europe, so it’s possible the results would be different for other populations, particularly those with more diverse genetic backgrounds or different customs for picking a marriage partner, Robinson said in the ScienceNode article.
Robinson added that he and his wife match the results of his study.
“Yes, we both have Ph.D.’s and we’re both tall,” he said in Science. “We fit the bill.”
