Ti måder DNA påvirker vores relationer.

1. Kærlighed er i luften: At sende og modtage usynlige signaler med duft.

Casanova bemærkede i sine erindringer, at 'jeg har altid fundet ud af, at den jeg var forelsket i, duftede godt, og jo mere rigelig hendes sved var, jo sødere fandt jeg den'. 'Det' Sweaty T-shirt experiments performed by Professor Claus Wedekind's laboratory demonstrated the scientific basis for "Casanova's sense for Chemistry", showing that opposites do attract genetically, but only at specific genes that encode the receptors for our immune system. Decades of experiments have shown that if a person’s natural body odour smells good then you will share different MHC genes, and you're biologically wired to be attracted to that person for a relationship or friendship. People who find each other's scent to smell awful are likely to share similar MHC genes and are unlikely to experience the feeling of “chemistry” in person. Sensing an unpleasant body odour is your natural warning signal to detect genetic incompatibility!

2. Mennesker opfandt kysset for at teste for genetisk kompatibilitet.

Our sense of smell detects molecular cues carrying information about genetic relationship and individuality. If we like the smell of someone then our biological instincts are activated, resulting in changes in our mood and social behaviour. During courtship the act of kissing allows us to get close enough to smell each other's natural body scent (Wlodarski and Dunbar., 2015).

3. Vores anden dato præference er påvirket af DNA kompatibilitet.

A recent study in an Asian American population has found the MHC-based attraction AKA "Romantic Chemistry" is just as important as personality in predicting second date offers (Wu et al., 2018).

4. Orgasme Styrke og Hyppighed Bliver Påvirket Af Genetisk Kompatibilitet.

Mænd, der opfattes som at have en behagelig duft af deres partnere, har vist sig at fremkalde højere intensitet og hyppighed af kvindelige orgasmer. (Sherlock et al., 2016).

5. Evnen til at fornemme 'kemi' med nogen handler om dine børn.

Præferencen for forældre med forskellige MHC-gener øger chancerne for høj MHC-variation og rekombination hos børnene, hvilket fører til forbedret modstandsdygtighed mod en række patogener. (Kromer et al., 2016) .

6. Genetisk uforenelighed kan påvirke affærer.

Det er svært at studere dette fænomen hos mennesker på grund af etik, men genetisk uforenelighed er blevet observeret ved at følge livet for den obligate parlevende dværglemur med fedthale, som opretholder livslange parforhold, men har en ekstremt høj forekomst af ekstra-par paternitet. Schwensow et al., 2008 Schwensow og andre, 2008 Forskning har vist, at ekstra-parrede parring hos dværglemurer forekommer, når par deler et signifikant højere antal MHC-supertyper med deres partnere, og at den utro partner vil finde en ekstra-parret partner med meget forskellige MHC i forhold til deres livspartnere..

7. De samme regler for genetisk kompatibilitet påvirker vores valg af venner.

En undersøgelse, der testede mere end en million DNA-data punkter i en befolkning af 1.367 venskabsparrer og 1.196.429 fremmede par, fandt ud af, at venskaber var mere tilbøjelige til at være mellem mennesker, der var mest forskellige på nogle få gen-sæt, der koder for lugte- og immunsystemsfunktioner. (Christakis and Fowler., 2014).

8. Familieplanlægning

The inability of a couple to conceive is a very difficult time in a relationship, and recurrent miscarriage is heartbreaking, sometimes this can be a result of both people sharing similar alleles in genes within the MHC complex. Studies have shown a strong correlation between miscarriage and similarity of HLA alleles. For example Ober et al., 1998 Viste, at der blev observeret signifikant øgede abortrater blandt par, der matchede for hele den 16-locus haplotypen, de evaluerede.. Mora-Sánchez og medarbejdere, 2019. proposed a genetic-risk calculation that could predict recurrent miscarriage (RM) based on analysing HLA haplotypes from couples either with histories of successful pregnancies. Interestingly the DNA Romance genetic compatibility rating can be interpreted in a very similar way, with high compatibility ratings correlating to MHC dissimiarity and low compatibility ratings associated with MHC sharing .

9. The Head Turner: We are wired with the instincts to help select the right partner for us!

Is that just a great perfume or colone? or did your head just turn for your one in a million match? Milinski and Wedekind., 2001 Udførte eksperimenter, der viste bevis for MHC-korrelateret parfumepræference hos mennesker, hvilket demonstrerer, at parfumer faktisk forstærker ens naturlige kropslugte, der svarer til deres immunogenetik. Disse resultater kan hjælpe med at forklare, hvorfor den samme parfume lugter anderledes på forskellige individer..

10. Du kan bruge DNA-matchmaking til at hjælpe med at forbedre din online dating-oplevelse og finde din livspartner hurtigere.

Online dating has dramatically changed the way we meet people, connecting us across different social circles and geographies but, you can't use all of your senses online. DNA Romance use understandings in the science of genomics and evolutionary biology to match single people with other's who are most likely to jive with them. Our DNA matchmaking algorithm, guides our users by showing MHC "dissimilar" individuals to have high compatibility ratings, a forecast of expected sexual chemistry between these individuals.
