我男友母亲那边据说是泰国的，他从小家里也是说泰语/法语。老一辈们之间，像父亲和他大伯及祖母会说潮汕话，一大家子聚在一起时通常是说泰语，方便长辈沟通和理解。整个家族，由于他祖父早逝我不清楚，沟通下来只有他祖母会流利的国语（带两广口音）。

男友从小一直定义自己为中泰血统的结合，五官特点也比较像泰国人，肤色倒是中等偏浅，他家如今沿用的姓氏拼写为An（后得知是到法国后改的姓），因此我确实也以为他的华人血统和泰国血统贡献了主要占比。

我们生活在海外，用23 and me做下来的基因报告并不太符合预期，转到微基因后，更是出现了日本人的血统，且两份报告中关于泰国的基因指向都非常少。

说得有点多，麻烦大家看一看，他究竟该如何定义自己的血统？
