DNA 影响我们人际关系的十种方式

1. 爱在空气中：用气味发送和接收无形信号

卡萨诺瓦在他的回忆录中指出，‘我一直发现自己就是那个人’爱上香香的，她的汗水越多我越甜找到了' 这 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. 人类发明了接吻来测试基因相容性

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. 我们的第二次约会偏好受 DNA 兼容性的影响

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. 性高潮的强度和频率受遗传相容性的影响

已经证明男性认为他们的伴侣有令人愉快的气味诱导更高的女性高潮强度和频率 (Sherlock et al., 2016).

5.与某人感知“化学”的能力完全取决于您的孩子

偏爱具有不同 MHC 基因的父母，增加了机会高 MHC 多样性和在儿童中的重组，导致增强对多种病原体的抵抗力 (Kromer et al., 2016) .

6. 基因不相容会影响事务

由于伦理学，很难在人类身上研究这种现象，但遗传通过跟踪义务人的生活已经观察到不相容性成对生活的肥尾侏儒狐猴保持终生的成对关系，但具有极高的双亲率。 Schwensow 等人，2008 年 发现侏儒狐猴的额外配对发生在夫妻共享一个与他们的合作伙伴的 MHC 超型数量显着增加，并且作弊的伴侣会找到一个具有非常不同的 MHC 的额外配对伴侣，相对于他们的生活伴侣.

7. 遗传相容性的相同规则影响我们对朋友的选择

一项在人群中测试超过一百万个 DNA 数据点的研究1,367 对友谊和 1,196,429 对陌生人发现了友谊更有可能在几个基因组上最不同的人之间编码嗅觉和免疫系统功能 (Christakis and Fowler., 2014).

8. 计划生育

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 表明流产率显着增加匹配他们评估的整个 16 位点单倍型的夫妇. Mora-Snchez 等人，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 进行的实验显示了 MHC 相关香水的证据人类的偏好，证明香水确实会放大那些与它们的免疫遗传学相对应的天然体味。这些结果可以帮助解释为什么相同的香水在不同的地方闻起来会不同个人.

10. 您可以使用 DNA 配对来帮助改善您的在线约会体验并早日找到你的生活伴侣

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.
