The reason why the little toenail has two petals

Toenails and fingernails are corresponding tissues that provide basic support for the image of the feet. Toenails are also the basic tissues that enable the human body to maintain balance and increase mobility. They have a very powerful hidden effect on people. Therefore, many people are very concerned about the health of toenails. Let's take a look at the reasons why the little toe nail has two petals. I hope everyone can understand.

Petaloid toenails, also known as "complex nails" or "petal toenails", are medically called petaloid toenails (PTN) or little toe complexes, which means that the little toe nail is divided into petals instead of a complete piece. In fact, petal-shaped nails are an autosomal dominant trait and cannot be used as a specific marker for a certain ethnic group. Furthermore, nation is a cultural concept rather than a biological concept, and strict bloodline theory is meaningless.

This little toenail is very mysterious in terms of anthropology and anthropology. Only the Han people with pure blood have toenails divided into two parts, with the outer part being smaller. This caused netizens to take off their socks and look at her feet. Some were proud of her "pure bloodline", while others were amazed by her "exotic look".

This type of double toe shape is common in East Asia, but it is most frequently seen among the Han people. According to folklore, it is a symbol of the big locust tree in Shanxi, and is believed to be a mark made by "splitting", which is unfounded.

The polydactyly of the little toe is not a deformity because it does not cause any functional impairment. It is a habit of the early ancestors of the Chinese nation who did not wear shoes when working. In later times, due to the lack of functional impairment and natural selectivity, it has been preserved to this day.

The morphology of the little toe is also a delayed characteristic. Some people do not show it when they are young, but it only develops obviously in adulthood.

The analysis suggests that flap-like nails are a heritable trait that is unrelated to gender. Some people do not have lobed nails at birth. The earliest one appears at the age of 1, and the latest one appears after the age of 5. Not all children born to parents with lobed nails have lobed nails. If one of the parents has lobed nails, some of the children may have lobed nails while others may not.
