Anonymous users2024-02-15I don't think this is a reliable statement, because the appearance of children is determined by the genes of their parents, and it is also affected by a variety of factors, and the appearance of parents is relatively similar.

Anonymous users2024-02-14From a genetic point of view, certain genes are also present on the sex chromosomes. Sex chromosome X is much larger than sex chromosome Y, so there are many more genes on the X chromosome than on the Y chromosome. As we all know, the sex chromosome of males is XY, of which the X chromosome is from the mother, and the Y chromosome is from the father. Females have xx sex chromosomes, one of which is an X chromosome from the father and the other from the mother, and the X chromosome from the mother is often "masked" by the X chromosome from the father, which is why "daughters are like fathers".

Anonymous users2024-02-13I think there is no scientific basis for sons to be like mothers and daughters like fathers, and the child's appearance is also related to genes.

Anonymous users2024-02-12Because it is inherited by chromosomal genes. In fact, there is no scientific basis, and heredity is mainly influenced by dominant genes.

Anonymous users2024-02-11It's not a coincidence at all, it's because the appearance of sons and daughters will be affected by the genetic factors of their parents, so after seeing a child, you can judge who the father of the child is. But there is no accuracy, and some children do not look like their parents.

Anonymous users2024-02-10From the perspective of biological development, the child's fertilized egg develops, so the genetic factors of the parents are also the same, I personally think that this is a coincidence, and the proportion of genetic factors is the same.

Anonymous users2024-02-09This is a common condition in which a child's appearance is influenced by genes and genetic material, but there is no accuracy.

Anonymous users2024-02-08The son is like the mother because the X gene of the boy's gene (xy) comes from the mother, and it carries more genes than the father's Y gene, and the daughter is like the father because the X gene on the father's side carries more carriers than the X gene on the mother's side, so the daughter gets more genetic information from the father.
Genetic base is also known as genetic factors, is a chemical that determines the genetic characteristics of organisms, has a complex structure, in the 46 chromosomes of a human fertilized egg, the chemical substance containing DNA is called a gene.
Genes are the main material basis for storing and transmitting genetic information and replicating cells, and the storage and transmission of genetic information from one generation of cells to the next and from one individual to its offspring involves a chemical mechanism.
Genetics hide the secrets of life and its history, and are born in the process of evolution of biochemical systems, one of which can faithfully replicate itself and maintain the basic characteristics of living things, and the other can "mutate".
People often say that sons are like mothers, daughters are like fathers, height and IQ follow their mothers, and their personalities follow their fathers, in fact, this statement has no scientific basis, children's appearance or IQ height, like who these things are not good, it is possible to look like mother, but the personality is like father, and the child's personality has a lot to do with the growth environment, and it is not necessarily innate, but most of the appearance of this problem is like dad or like mom, of course, some children may be like dad, Part of it like mom, that's the power of genetics. <> >>>More
In my opinion, the reason why Chen He's daughter looks like a "human elf" is that she looks very cute. The lowly Zeng Xiaoxian in "Love Apartment" is really interesting and cute, and Chen He is even more famous for playing Zeng Xiaoxian. Chen He met Zhang Zixuan through filming. >>>More

Everyone's heart is different, the growth environment is different, the things they come into contact with are different, and more importantly, they feel different. Other people's solutions are not necessarily their own. And watching something sad to make yourself cry is also a good solution, imagine the feeling of holding back your tears and letting it flow quickly, isn't it different? >>>More
