All baby boys look like their mothers. Do you know why?

When you first see a child, you can't help but tell whether the child is a little like his father or a little like his mother. In most cases, you will say "the child looks like his father" or "the little girl looks exactly like her mother when she was a child".

As for who is more like him, it seems that there is not much periodicity to talk about. In some cases, he looks more like his mother, while in other cases, he looks more like his father. There are different suggestions on who boys look like, so how can some boys look like their mothers and some like their fathers? Is there any law in the inheritance of children's appearance?

1. Children's appearance is influenced by genetic factors. The various features of children's facial features do not come out of thin air, but are propagated according to their parents' genetic inheritance. Therefore, the child's appearance characteristics basically depend on the parents' appearance to evolve the development trend, so there will be disputes about who the child looks more like.

As far as microbial inheritance is concerned, children's facial features are mostly similar to their mothers, which is caused by different nuclear components in the middle of sperm and eggs. Compared with the "huge" size of egg cells, the size of male sperm is "petite", so the accompanying nucleus is smaller, and the genetic influence on children's five senses is smaller than that of mother's egg cells.

2. Who does the child look more like? There are certain psychological factors. Many times, everyone who looks like at first sight will be influenced by some psychological factors. If we subjectively think that a baby should be more like a father, then the child will look more like a father, and sometimes feel more like a mother, so it will be more like a mother. This is also the unconscious influence of mental state.

Some babies are likely to look more like one of their parents in appearance and facial features, but the overall charm and expression will bring the charm and feeling of the other. Such items are also very influenced by people's "I think", which will lead to different people's different views on who they look like.

3. Genetic law of children's five senses 1. Genetic inheritance: in the inheritance of children's five senses, no matter who they look like, most of them follow the regularity of genetic inheritance. In other words, children's facial features basically come from genetic inheritance between parents, and these characteristics as genetic factors will be hidden and will not be highlighted.

Among the five senses, the characteristics attributed to dominant gene inheritance are: double eyelids, big eyes, eyelashes, high nose bridge, hairline and pear vortex. If the other parent has these five facial features, then the child will have a high probability of inheriting this feature, which is also the primary reason for the similar appearance.

2. Mutual inheritance: To put it bluntly, in other words, parents' genes have half influence on each other and have the same influence on children's looks. In this inheritance, skin color and size are the main factors, and children's genetic genes account for 50% of their parents, which is a fair way of inheritance.

In other words, if one parent has a dark skin color and the other has a white skin color, then the child's skin color is the median of the parents' skin color. Similarly, a child's height is also the median of parents, but different from skin color, the child's final height is affected by genetic factors, and 30% of the child's height is affected by acquired environmental factors.

Important Tip: Children's appearance is mainly influenced by their parents' genetic genes, while children, on the one hand, are somewhat like people with objective facial features and will continue to be influenced by their own psychological factors, while the genetic law of children's appearance is mainly influenced by genetic inheritance and mutual genetic combination.
