Many people think that the arrival of a special person in your life is an accident. According to a study, we choose a partner that is just like us.
When finding the right partner, there are several things that we focus on. We pay attention to height, intelligence, body weight, and many other factors.
It was mentioned in the study that we are actively seeking people who have a similar genome to ours. For instance, a tall person doesn’t accidentally find a tall mate.
They seek them out; these preferences are shaping our genomes.
In this post, we have discussed how our genes play a crucial part in searching for a partner. Have a look.
A study was conducted at the University of Queensland, Australia. In this study, it was found that people focus on similarities when looking for a partner.
The team picked 24,000 married couples with European ancestry. The team of geneticist used large databases, which included information like genetic and human physical traits.
They highlighted the genetic markers of one of the partners and predicted the height and weight of their partner. After that, the researchers compared their predicted height with the actual height of their partner.
At the end of the study, the scientists found that there was a strong connection between the actual height of their partner and their genetic markers for height.
Additionally, they also found a relation between BMI gene of people and their partners BMI. This study provides proof of assortative mating in humans.
In assortative mating, people mate with individuals with whom they have some similarity.
The scientists even test assortative mating based on other traits. In the UK database, 7780 couples were selected, and the focus was on years of education. They were looking for a connection between the genetic markers of the partners. It implies their focus is on similar interests rather than on actual years of education.
According to a postdoc in the lab of geneticist Peter Visscher at the University of Queensland, Matthew Robinson, assortative mating has a direct impact on the genomes of traits in people. With the help of these findings, a more accurate genetic model can be developed. This will help in understanding how family members inherit physical traits or diseases.
Furthermore, Robinson wants to conduct research on why spouses have similar behavioral traits like political preference, psychiatric disorders, and IQ.
Therefore, it is concluded genes are a key factor when choosing your life partner.
