The service is being offered online by a number of companies, including Scientific Match and the Swiss company, Gene

Both were inspired by the infamous 1995 ‘sweaty T-shirt’ experiment in which women were asked to sniff the T-shirts of similarly aged men and rate their body odours as proof that DNA matching works.

Influential, motivated, insightful, and highly intellectual are words that best characterize Water Snakes.

'And on the subject of DNA compatible partners having healthier offspring, Ms Berry adds: 'I’m sure our ancient ancestors would never have survived if they had not used these natural instincts, or ‘natural selection’ for want of a better phrase.

If a man and a woman are going to breed successfully, a wider spread of genes and immunity to disease and deformity would obviously be better for the child’s survival.'While she doesn't completely dismiss Gene Partner’s claims and believes such genetic 'engineering' could be hugely significant for people who have a family history of illness or disability, Ms Berry acknowledges that it might not be viewed as ethical by some. I rely on my personal touch, enabling and encouraging my clients to keep an open mind and to get out and meet as many people as possible. But sometimes you need to kiss a few more frogs to find your Prince.' Attraction based DNA was first studied in 1995 by Claus Wedekind.

The Gene Partner project was inspired by a study carried out by Prof Dr.

Wedekind at the University of Bern, Switzerland, in which he asked women to smell the T-shirts of various men and rate them for attractiveness A detailed explanation of why DNA match profiling works is given on the companies website.

It states: 'High diversity in specific immune system components ensures greater resistance against a variety of diseases'Our bodies automatically sense how diverse the immune systems of people around us are, and we subconsciously classify them depending on how genetically compatible they are to our own.'With genetically highly compatible people we feel that rare sensation of perfect chemistry.

This is the body’s receptive and welcoming response when immune systems harmonise and fit together.'The site claims that genetic compatibility results in 'an increased likelihood of forming an enduring and successful relationship, a more satisfying sex life and higher fertility rates.' A definite plus when it comes to online dating, which can often mean having to endure dozens of one-off dates before finding someone worth getting to know better.This is especially evident in the home, where luxurious furnishings and surroundings help Snakes seek the peace they need in order to thrive.Snakes prefer living a life of calmness, preferring quietness over noise and a manageable workload rather than a schedule that’s overly-booked.The women were then asked to rate how 'sexy' they thought the t-shirts smelled and the findings revealed a link between how good the shirts smelled to them and how dissimilar their immune DNA was to that of the man in question.Nowadays, scientists believe that what we refer to as 'chemistry' when we meet someone new is actually the body's natural response to two immune systems connecting and recognising that they fit well together because they are genetically dissimilar.Snakes become easily stressed when their lives aren’t peaceful or in order.
