Causes of baby's thick lips

In real life, many parents have found that their baby’s lips are a little thick, which affects their appearance. Some babies have thin lips, which makes their mouths look small, while some babies have very thick lips. Many parents wonder why their babies are so small, but have such thick lips? What is the reason for this? Let’s take a look at the back of the baby’s lips.

Genetic factors:

There is indeed a saying that "children look more like their opposite-sex parent." But in fact, from facial features such as eyes, nose, and mouth to body shape, children inherit genetic factors of various physical elements from their parents at the same time. Since the influence of genetic factors obtained from mom or dad is the same, it is unscientific to say that the opposite sex has a greater influence. Therefore, although this statement is widely circulated, it has no scientific basis. It is probably just a rough judgment based on some of the features shown on the child's face.

All of your traits have the same chance of actually being passed on to your children, whether you want them to or not. Whether a child exhibits certain genetic traits depends mainly on whether the trait is dominant or recessive. Dominant inheritance refers to inheritance that can manifest characteristics under the influence of the genetic factors of one party, while recessive inheritance refers to inheritance that requires the genetic factors of the father and the mother to pair up to manifest characteristics. For example, if the mother is type B blood, the father is type A blood, and the child is type O blood, then the type O inherited by the child is what we call recessive inheritance. In other words, the mother is type BO blood and the father is type AO blood, and their O-type genetic factors pair up and are inherited by the child. Therefore, it is believed that the flaws in parents’ appearance are more likely to be passed on to their children.

It is difficult to say which parent's characteristics are more likely to be passed on to the child. It is common in real life that both parents have good looks but the child is average looking, or that both parents are not good looking but the child is very good looking. Facial features are also passed on to children through genetic factors that carry the characteristics of each element. In reality, there are cases where the shape of some children's eyes, nose and mouth are very similar to their mother's, but the layout and position are very similar to their father's.

The child's father shares 50% of his genetic genes with his biological brother, and the same is true for the child's mother. The child's father or mother shares 50% of the same genetic factors with the child. So the child shares 25% of the same genetic factors with his uncle or aunt. Therefore, based on genetics, it is not surprising that a child looks similar to his uncle or aunt. If you feel that your child looks more like his uncle or aunt than his parents.

Double eyelids are easily passed on to children. Because double eyelids are dominant and single eyelids are recessive, the genetic factors of double eyelids are more likely to show on the surface. If both parents have single eyelids, the child will generally also have single eyelids. If both parents have double eyelids, generally speaking, the child should also have double eyelids, but occasionally the child may have single eyelids. The reason for this change is the same as the reason why a couple with blood types A and B give birth to a child with blood type O.

What is described in the above article is a detailed introduction to baby's thick lips. I believe that parents and friends have a deeper understanding of the problem of baby's thick lips after reading this. At the same time, the baby has a lot of room for growth, and there will be many changes in the process of growth. Some babies are completely different from when they were children when they grow up, so parents and friends don’t need to worry.
