Is there a scientific basis for the saying daughters are like fathers, sons are like mothers ?

According to social experience, there is some truth, but there is no scientific basis.

Because the father's chromosomes are divided into x, y, and the mother's is x, x

Gender is determined by y, and most of the others are determined by x.

So when giving birth to a boy, his x must have come from his mother, so like his mother.

As for having a daughter, it's hard to say.

Yes, because the father's chromosomes are divided into x, y, the mother's is x, the x sex is determined by y, and most of the others are determined by x.

So when giving birth to a boy, his x must have come from his mother, so like his mother.

As for having a daughter, it's hard to say.

Hello! It's a common saying, and there's some truth to it, but it's not entirely true.

From 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".

The laws of heredity are very complex, and the ways of inheritance are also diverse. Who is the child like? For example, whether you are as tall as your father and whether your eyes are as big as your mother's eyes are not yet possible.

The son's X chromosome comes from the mother, the Y chromosome comes from the father, and the Y chromosome is smaller than the X chromosome and carries fewer genes, so the genes carried by the X chromosome are more easily reflected.

There is a scientific basis for this, scientists only say this after studying the genetics, the daughter's genes are more like the father, and the son's genetic combination is more like the mother.

There has always been such a saying among the people:The daughter looks like her father, and the son looks like her mother。Is this true? Let's take a look.

Numerous scientific studies have shown that a child's IQ is mainly inherited from his parents, while a daughter's IQ is mainly inherited from her father, which is genetically determined. For example, if the father's IQ level is relatively high, the daughter's long IQ is generally higher.

Eyelashes: Long eyelashes are also dominantly inherited. As long as one parent has long eyelashes, it is very likely that the child will inherit long eyelashes.

Double eyelids: Double eyelids are dominantly inherited, and the baby born with single eyelids and double eyelids is very likely to have double eyelids. But both parents have single eyelids, and children in general also have single eyelids.

Nose: In general, the nose is large and tall and has wide nostrils. One of the parents has a straight noseThere is a high probability of passing it on to children

The inheritance of the nose will continue until adulthood, with a short nose as a child and a tall nose as an adult.

In general, because of heredity, whoever has a dominant gene will be like whom, this is not fixed, probably most boys are like mothers.

I don't think this is necessarily true, there are also daughters like mothers, sons like fathers.

Because many family children are like this, so I say so.

Because it's genetically determined! Many of the daughter's genes depend on their father, and the son's genes depend on their mother.

I think it may be that the daughter inherits more genes from her father. Sons inherit more of their mother's genes.

This may be because many families are like this, but it is not necessarily.

Because many people are like this, there are such sayings that have been handed down.

Maybe it's because of genetics, but it's normal.

I think it's mainly because the daughter's genes reveal a lot of her father, after all, this still depends on the genes.

Because this thing is genetically shown to be like this, so it is said to be the same.

It'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.

From 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.

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

1. Dad is the earth, Mom is a fine flame to shelter from the rain, and the little daughter is like a little sapling growing into a big tree.

2. Dad is the spring breeze, mom is the drizzle, and the little daughter is like a little grass that has just spit out its buds in the spring.

3. Dad is a green leaf, Mom is a green leaf, and the little girl is like a flower, opening in the middle of the green leaf.

4. Dad is Wang with the sun, Mom is rain, and the little daughter is as delicate and blooming as a flower.

5. Dad is a branch, Mom Pizhou is a flower, and the little daughter dances in the middle like a bird.

6. Dad is a string, mom is a string, and the little girl plays and sings the two strings like a song.

Not necessarily, although personality has a lot to do with family education, there is no certain statement about whether the child's personality is like a father or a mother.
