DRom 1.0 Predicts "Chemistry" Online

DNA Romance predicts "Chemistry" online using DRom 1.0 an algorithm that considers 100 Single Nucleotide Polymorphism (SNP) markers positioned in candidate genes that have been shown to play a role in human attraction and reproduction. Research demonstrates that people with differing DNA markers find each other’s scent to be pleasant and are more likely to have a lasting romantic relationship.

Our Backstory

We are all biologically programmed to know if we are compatible with somebody or not, this is one of our instincts. Our bodies are informed and respond to information received from our senses when we meet in person.

DNA Romance started with the knowledge that DNA can influence relationships. The technical founder, Dr. Timothy Sexton (Tim) holds a Ph.D. in population genetics, and a Bachelor of Science in biochemistry and molecular biology. This education has provided him with a good understanding of how genes work, how the genes adapt to different selection pressures, and how this shapes the evolution across populations of other individuals. In 2012, he met Judith Bosire online and they started dating; Judith was coming from a business background, which complemented Tim's education in genetics. They had met using an online dating site, and a discussion arose from them comparing their experiences using online dating apps. They agreed that a major frustration about using “online dating platforms” was the mismatching, especially for “chemistry”. When you meet in-person, you know right away if you have “chemistry” or not. But, when you are online, it’s impossible to evaluate if you share “chemistry” with someone, you can only detect “chemistry” when you meet in person.

Both Judith and Tim had horror stories of online mismatches, suitors that seemed promising until the first date, when it was instantly and mutually realized that there was no chemistry. This gut feeling of “chemistry” is your body’s natural radar to detect a person who is genetically compatible with you. Tim explained the so-called "sweaty T-shirt experiments," which proved a definitive link between DNA and romantic attraction. In the first experiment by Prof. Claus Wedekind in 1995 where 49 female students and 44 male students were recruited. The men were asked to wear the same T-shirt for two nights (Wedekind et al., 1995). The female participants were asked to smell each shirt and describe how pleasant they smelled on a scale of 1 to 10. The results showed that women found male body odour pleasant when the male participants were far more genetically different at a specific set of genes called the Major Histocompatibility Complex (MHC). In contrast, the women found male body odors to be unpleasant when the male participants were genetically similar at the MHC genes. Independent research has continued to validate these findings. These genes didn’t only play a role in human attraction. Previously, these same genes had been shown to play a key role in “mate pairing” in other vertebrates, including primates and birds that partnered for life.

The founders' discussion about the basis of “romantic chemistry” was truly fascinating; there were several hypotheses that could explain why we like the scent and share “chemistry” with people who have different MHC genes. After all, these genes encode MHC peptides, which cover the surface of your cells and are critical for your body’s recognition and response to foreign pathogens. We are attracted to people who are different at these genes, because the success of the human population depends on this mechanism to maintain diversity at immune system genes. This ensures that some individuals are resistant to new pathogens, and no cold or flu virus would wipe us out. In addition, if Mum and Dad have different immune systems, they won't always get sick from the same illnesses and can look after each other.

Judith asked, "Why isn't this DNA information being used for online dating?"" Tim knew he had the skills to build “DNA Romance” and he pictured this as something easy to do, especially with a business-minded partner. Together, they took on the challenge to start DNA Romance, and in 2014, they incorporated the company. In 2016, Tim quit his job to begin working on DNA Romance full time, and a year later, in September 2017, they launched DNA Romance to the public.

We've been asked by customers to include race but the definition of race is ambiguous. To allow people from minorities to find each other, we have provided options for matchmaking based on similar geographical location and shared religion or life philosophy.
We certainly agree with the words of Jane Elliott: "There Is Only One Race. The Human Race". So DNA Romance doesn’t use race to describe the many different phenotypes of humans resulting from differences in population ancestry.
While we do appreciate a person's preference for different colours, we are still considering how to thoughtfully accommodate our customers' preferences. Please send us an email if you have any helpful suggestions on this topic.

We accept your autosomal DNA data from several 3rd party DNA testing companies, please login to your account with the company who did your DNA testing (either ere are instructions to login and download your data from either: 23andMe, or Ancestry DNA, or Family Tree DNA, or We Gene, or My Heritage, or Dante Labs, or Genes For Good, or Vitagene, or Living DNA. and request to download your raw autosomal DNA data. Once your raw DNA data is downloaded, save it to a secure location and then use this file to complete your DNA Romance profile.

Yes, evidence from several studies show that the same rules of attraction also apply for relationships between people in the LGBTQ community.

To assist with our guidance on relationship compatibility, we have developed a scale that uses the 16 personality types from the Myers Briggs test, and provides maximum weight to compatible personality types, and less weight to personality types that tend to clash.

Research shows that the rare sensation of chemistry is felt by people who are genetically compatible. Our bodies are naturally programmed to feel receptive and welcoming to people who are genetically compatible. You can read more about how the genes for love influence our feelings of "romantic chemistry", as well as influence other aspects of our relationships.

Each of us has a unique combination of several hundred genes, corresponding to our immune responses, which protect us from some diseases and not others. Everyone is different and no one person is resistant to every disease known to humanity.


Our sense of smell (olfactory system) is so highly evolved that we will find someone’s smell to be pleasant if they are resistant to diseases that we aren’t. Our sense of smell is wired to our brain and detects potential relationship partners who are resistant to different diseases. This is important, because when one partner is sick, then the other might remain healthy. Furthermore, children will inherit a more diverse set of genes from their parents (protecting them from more diseases than either parent alone).


The relationship between immune system genes and attraction (mate-pairing) is not exclusive to humans, major histocompatibility complex (MHC) dependent mate selection has been described in many vertebrates including fish, birds, and primates. Please refer to our blog and reference list for dozens of research papers describing this phenomenon.

Stigmatization and discrimination are important concerns when using new technologies and we respect individuals and their personal choices, regardless of their genetic, socio-economic, ethnic, cultural, educational, and religious backgrounds. We oblige global policies such as The Genetic Information Nondiscrimination Act, which was passed to bar the misuse of genetic information in the United States.

Olfactory is another word for your sense of smell, and what's interesting is that you can actually smell other people's scent profiles which correspond to different immune receptor proteins. If their natural body odor smells good, then you have different MHC genes and will be attracted to that person for a relationship or friendship. If they smell awful, then they are likely to have similar MHC genes to you and there is probably no sexual “chemistry” between you two.

DNA can be collected in many ways but DNA Romance use the "Cheek Swab" method. Our DNA Collection kit is simple to use, just swab the inside of both cheeks and return your sample to the laboratory by mail! No blood, no pain, no sweat!

If you already have raw DNA testing data from 23andMe or another DNA testing company, simply upload your raw autosomal DNA to you profile and your matches should appear within ~2 minutes. If you don't receive your matches within an hour, please check your file is correct, and if the problem persists, please email tim@dnaromance.com

The DNA testing takes 3-4 weeks to complete based on the time your samples arrive in the lab. You can order your personal DNA testing kit now.

Your genetic data is encrypted once you upload it to DNA Romance, and then, the relevant DNA markers will be incorporated into our matchmaking algorithm. Within ~2 min, you should see your DNA Romance matches.

Our DNA romance score reflects your potential for chemical attraction with another person, but this is not everything in a relationship. We do our best to provide additional matchmaking information by including a personality compatibility score, and showing a picture, but every person is an individual with different experiences. Like any online dating site, DNA Romance provide a short-list of matches with whom you can communicate and see if there is a meaningful connection. No dating site can replace the need for a first date, to look each other in the eyes, talk, smell each other and mutually see if there is a meaningful connection.

There are many options for a first date, depending on your surrounding location. A date usually involves a meal or drink. The classic first date is a chat over coffee or tea, but alternatively, you could ask them out for lunch or dinner. During the pandemic, we encourage you to make a video call to get things started. Some first and many second dates onwards involve an activity like ten pin bowling, or going to a sports game. After a good first date, you should follow-up and suggest a second date.
As for the dress code, we recommend that you gauge this based on your proposed location and activity. In most instances, smart casual is a safe bet.

Yes, our affiliate/partner program rewards you with a commission for every person who finds us, based on your referral and makes a purchase. In addition, our affiliates receive ongoing commissions, based on the activity of other affiliate marketers you refer to us.

How similarities or differences in MHC alleles can influence family planning

MHC similarity between couples is known to cause issues with family planning, here are some of the peer-reviewed papers describing the role of MHC similarity and human reproduction.

Personality Types

Our personality compatibility rating is based on the Myers-Briggs 16 personality types. This test has a long history with the development of the first 3 components dating back almost 100 years to Dr. Carl Jung and today the 4 letters and 16 personality type groups are widely known to the majority of people. DNA Romance's personality compatibility algorithm, called PC1, puts maximum weight on similar personality types and less weight towards personality types that tend to clash.
