Genetic predisposition to love

There is a theory that our preferences in choosing a partner are determined by biological factors. Research shows that people are subconsciously drawn to those whose immune system (MHC - major histocompatibility complex) differs from their own. This explains why we are attracted to certain smells - they carry information about genetic compatibility.

Scientists suggest that couples with more different MHC genes have a better chance of successful relationships and healthy offspring. Such partners are more likely to experience mutual attraction, and their children inherit a stronger immune system.

Biochemistry of love

Love is not only emotions, but also a complex chemical process. At different stages of a relationship, different hormones are activated:

Phenylethylamine (PEA) – causes euphoria and "butterflies in the stomach", it is responsible for the first stage of falling in love.

Dopamine – a pleasure hormone that strengthens the bond between partners.

Oxytocin – an attachment hormone that increases in long-term relationships and after physical intimacy.

Vasopressin – helps to form emotional attachment and loyalty to a partner.

Is it possible to "pick" the ideal partner by DNA?

Recently, companies have appeared that offer genetic compatibility tests. They analyze the DNA of potential partners to determine how "suitable" their bodies are for each other. However, science still does not give a clear answer to the question of whether it is possible to guarantee a successful relationship based only on genetics.

Relationships are not only about biology, but also about psychology, social experience, values, and interests. Even if a couple has “perfect” DNA compatibility, this does not guarantee that their outlook on life and emotional needs will coincide.

Conclusion

DNA compatibility is a fascinating area of ​​research that may become more important in the future. However, for now, love remains a complex combination of biology, emotion, and conscious choice. So, despite scientific discoveries, sincerity, trust, and mutual understanding in relationships remain the most important.
