Is it Liu Jiafan of "Central Plains" descent or the so-called "Na Man" descent?

Liujiafan has nothing to do with ethnic origin, but is a genetic disease.

Petal nail is an autosomal dominant trait, and the genotypes of a couple of Han people with petal nail may be dominant, but their children may have several genotypes after pairing. Then, there will be some children who are not petal-shaped nails. It is obviously impossible to distinguish nationality by armor.

In other words, Jia is not directly related to his nationality. Even in Hongdong County, Shanxi Province, the legendary birthplace of immigrants, not every Han population has scorpions. Even brothers and sisters in a family, scorpions appear differently.

Chaoshan people are called Liujiafan.

Many Chaoshan people have the characteristics of split toes and nails, so they are called "Liujia rice". Physiologists believe that this is the legacy of racial hybridization, and some historical researchers regard it as the basis for exchanges between Chaoshan area and other races since ancient times.
