We have an old saying in China: the nine sons of the dragon are different. But we folk also have such a saying: "Dragons give birth to dragons, phoenixes give birth to phoenixes, and rat sons love to punch holes!" These are all handed down from the ancestors, so does these two sentences sound contradictory together? In fact, science has already given us the answer.
The so-called dragon and phoenix are only the result of heredity. The nine sons of the dragon are the children of the dragon, and they also have different personalities. But for modern society, the latter statement, we basically can't use it, because our current fertility is really low. There are only one or two left in the family, and the difference between giving birth to a child is still not large, and it basically does not escape the influence of genes on children.
First, let's talk about the genetics of intelligence
For a child, the intellectual factors inherited by the mother to the child are more powerful, but due to the difference in factors such as the environment and education in the later stage, each child's strength level is about 40% to 50% of the room for improvement.
Therefore, some couples with a low IQ should not be too anxious, you can use the acquired power to create an educational environment more suitable for their children to grow, maybe your children can counterattack you.
And some couples with very high average IQs don't need to be too excited, because in a survey in the United States, the average proportion of children born to couples with an IQ of more than 140 is only 127.7. It can be seen that although the child's IQ level will be affected by the genetics of the parents, the influence of acquired factors is also useful.
Second, let's talk about the relationship between height and heredity
Similar to intelligence is height, which can also be self-improved through acquired adjustments. Some children's parents are not tall, but the children have surpassed their parents and grown to an average height, although they have not grown into Yao Ming, but this is already for a family, and the children can grow tall in the future. This can also be regarded as a counterattack on the height of a family, a successful case!
Third, the next thing is the fat and thin inheritance that we care about
It is very regrettable to tell families that if one of the spouses belongs to the little fat man, the probability of the child becoming a little fat man in the process of growing up will increase to at least 80%. And one party in a family belongs to a small skinny person who is not fat at all? Then his children are likely to have this kind of physique.
Fourth, the genetics of looks is the focus of many parents' concern
Whether a child looks like a mother or a father depends on the child's gender, and at the same time, it also depends on who is more genetically strong, both father and mother. Around us, we will find that many boys may be more like mothers, and girls are more like fathers, although there is no scientific basis, but at least the actual situation around us makes us have this illusion.
In fact, the physiognomy characteristics of parents are inherited from their children at the same time, but the characteristics inherited by each child are not very consistent. Some features are more pronounced like mom, while others are more pronounced like dad. Of course, are there also some children like that? Not with the parents, nor does it rule out the genes of the child, which may be more inherited from other elders and blood relatives.
Fifth, the color of the skin is also inheritable
This does not need to be said more, black children are black skin, white children are white skin, and our yellow children are naturally yellow skin, but relatively speaking, if our skin skin is whiter, then the child's probability increases by 50%. If one of the spouses has white skin and one has a dark complexion, the child's skin is likely to be brown.
On the road to parenting, we are all novices, how to take better care of children, you can pay attention to me, and discuss with me those things on the road to parenting.
