Men and women have a "type," and tends to be someone who looks like their mother or father, according to new research.
When it comes to looking for a long-term partner instead of a sexual adventure, men will go out with women with the same or similar color of eyes and hair as their own mothers.
Women will choose a long-term male partner with the same eye and hair as their own parents, provided that he was present during his childhood.
The scientists said that we are unconsciously "printed" to look for partners who look like our parents from an early age.

Men and women have a & # 39; type & # 39; – and it tends to be someone who looks like his own mom or dad. When it comes to looking for a long-term partner instead of a sexual adventure, men will go out with women with the same or similar color of eyes and hair as their own mothers (file image)
Researchers from Charles University in Prague analyzed the past and current relationships of almost 1,900 heterosexual adults.
They compared the color of eyes and hair of each partner with that of their father of the opposite sex.
Both men and women tended to choose long-term partners, rather than sexual partners, who had the same eye or hair color as parents of the opposite sex.
One factor could be "imprinting," wrote the researchers, led by Dr. Karel Kleisner, in the journal Evolution and Human Behavior.
People often & # 39; internalize & # 39; the characteristics of their parents to such an extent that they unconsciously choose couples with similar physical characteristics.
Previous research has affirmed that we are attracted to people similar to our parents, since they were our first experience of a close relationship, turning them into a template for all our futures.
The eyes and hair not only mean attractive but other qualities: the lack of gray suggests good health, although some gray hair in a man can transmit reliability, the research said.
The eyes can also represent all kinds of characteristics from the domain to the goodness according to previous studies.
But by choosing long-term partners who look like parents, there are more chances of producing children that look similar to previous generations of the family.

This may be a subconscious evolutionary choice like that observed in animals to keep the family line strong and healthy.
And although adults can choose a partner who looks like their parents, they will also reject them if they had an unhappy childhood, the researchers said.
Survey women whose father did not live in their home during their childhood were less likely to choose a future partner with the same eye or hair color.
The researchers reported: "It seems that when it comes to eye and hair color, people have their 'type' and prefer a non-random feature.
"We have come to the conclusion that an effect similar to printing has a greater influence on the modulation of the partner's choice.
"The strongest similarity between parents and peers was found in cases where parents share the same eye color.
"It suggests that long-term mating is less random than short-term mating.
"Individuals are more likely to experiment in terms of short-term partners because they are evolutionarily relatively less important than long-term partners."
ARE MEN WITH SHORT AND WIDE SIDES MORE EASY TO TREAT?
Researchers from the Nipissing University in Canada observed how different facial characteristics affect sexual behaviors.
The study involved 314 undergraduate students who were in romantic relationships.
Each student completed a questionnaire about their behavior, sexual desire, sexual orientation, the possibilities that they considered cheating and how comfortable they felt with the concept of casual sex.
The researchers also took a picture of each student to analyze their facial width-height relationship (FWHR).
Scientists have discovered that men and women with short, wide faces are more sexually motivated and more likely to cheat than people with faces of other dimensions. In the photo, soccer player Wayne Rooney, who previously cheated on his wife, Coleen
The results showed that men and women with a high FWHR – square and wide faces – reported a higher sexual drive than others.
Men with a larger FWHR were also easier when it came to casual sex and would consider being unfaithful to their partners.
The researchers hope the findings shed light on the role of facial features in sexual relationships and partner selection.
His research is based on previous studies that have shown that certain psychological and behavioral traits are associated with proportions of facial width / height (FWHR).
Square-faced men tend to be perceived as more aggressive, more dominant, less ethical, and more attractive as short-term sexual partners than men with thinner and longer faces.
