What genes are typical of passing on male but not female , and it is best to have a daughter if eit

Bald. Although there are many main causes of baldness, such as too much stress and poor hair quality, there is another factor that cannot be resisted, and that is genetic inheritance. Baldness is one of the most typical symptoms that spreads to men but not to women, and you will see that many men have baldness, but women do not.

Since the gene that manipulates baldness is evident in men, it is latent in women. If a man is bald, the eldest son will also be bald, so couples with these problems may pray that they can have a daughter.

Haemophilia. Hemophilia is a chain recessive genetic disease, and the onset gene is generally carried by women, but women themselves do not suffer from hemophilia, and most of them are sent to their sons. Hemophilia is still quite harmful to people, once the patient has a wound on the body, there may be unstoppable phenomenon, and in severe cases, it will lead to blood loss, syncope and other conditions.

Therefore, if a woman has this diseased gene, it is recommended that it is safer to have a daughter.

Red-green color blindness. Red-green color blindness is a disease that everyone is familiar with, especially in color, patients will not be able to distinguish traffic lights. The high-risk group for this disease is men, and although red-green color blindness is not a problem and does not harm our bodies, it is likely that there will be certain restrictions in the choice of work.

For example, a man with color is not able to do the work of having to distinguish colors, like a driver. In addition, there is still a certain danger to daily life, such as not being able to distinguish traffic lights when crossing the road. If either spouse has this type of gene, it is advisable to have a girl.

How to give birth to a healthy and intelligent baby?

Do a good job of premarital check-ups.

In order to give birth to a healthy and intelligent baby, it is the most basic standard for the couple to have a healthy body. Therefore, before making up their minds to have a baby, it is best for both of them to go to the hospital for a regular physical examination of the whole body, and check whether there are some pathogenic genes on the body, which is also responsible for their future baby.

Folic acid supplementation in preparation for pregnancy.

Folic acid tablets are a type of vitamin, and its greater effect is to prevent fetal malformations. Scientific research has confirmed that in the first 3 months of pregnancy, if women can take an appropriate amount of folic acid tablets every day, they can greatly reduce the risk of neural tube defects in the fetus. Therefore, when preparing to get pregnant, couples need to pay attention to folic acid supplementation, which can help you give birth to a healthy and intelligent baby.

Progressive muscular dystrophy, a condition that is usually inherited only in boys, and may manifest itself in muscle weakness, muscle atrophy, and even unusual difficulty swallowing. It's better to have a daughter and be healthier.

Color blindness, bleeding disorders, baldness, these problems are transmitted from male to female, indicating that these diseases also have genetic factors.

If the husband has baldness, he may pass it on to his son, and the son will also have baldness when he grows up, so it is better to have a daughter.

Baldness, color blindness, and fava bean disease are inherited from either parent.

The first hereditary disease that transmits male to female is hemophilia, which will be affected by genetic genes, followed by hypertrophic progressive muscular dystrophy, and third, red-green color blindness, color blindness is also a disease that is transmitted from male to female. If the mother is red-green color blind, then the son born may be red and green color blind, but the daughter born is generally normal.

In genetics there are three diseases that are not transmitted from male to female, including color blindness, baldness and hemophilia, so people who suffer from this disease between parents and immediate relatives must pay attention.

No, it's just that some genetic females are more than males, but they should all be solved by now!

According to scientists, couples with bad habits such as smoking are more likely to have girls.

related, because chromosomes are DNA

There are some genetic diseases that only men suffer from, while women rarely suffer from them, and vice versa. Therefore, this genetic disease is sex-related inheritance. Because some genetic diseases are inherited through the Y chromosome!

A normal person has 23 pairs (46) of chromosomes, of which 22 are autosomes and the remaining pair is a sex chromosome, which is represented as xx for females and xy for males. There are many ways of inheritance of genetic diseases, some are autosomal inheritance, some are companion inheritance, this pathogenic gene exists on the sex chromosome, most of the common companion inheritance is on the X chromosome, then for females, two X chromosomes have pathogenic genes to get sick, but for males, he only has one X chromosome, so as long as this X chromosome has the pathogenic gene, it will be diseased. So there are some genetic diseases, it is true that the heritability rate of men will be higher, such as baldness, if there are male elders in the family who are bald, there will generally be many male members who are also bald.

This is a kind of genetic disease that "passes on to men but not to women", and genetic diseases such as red-green color blindness and hemophilia are "patriarchal".

In daily life, there are many genetic diseases that are more common in men than in women, such as the red-green color blindness and baldness mentioned above, as well as hemophilia, if you have this disease, the patient will be injured and will bleed under the skin, and Duchenne muscular dystrophy, which is a disease caused by genetic defects, which can cause muscle changes, paralysis and even death.

Genetic diseases are very complex, for modern medicine, there is still a lack of special methods for various genetic diseases of human beings, which can only be based on prevention and need everyone's attention, so what do you think about the problem of genetic diseases?

Because some diseases are inherited with the Y sex chromosome, they are not transmitted to girls.

It's all about genes and chromosomes. Some genetic diseases are transmitted only to males and not females, and are related to gender.

Because some genetic diseases are inherited through the Y chromosome! The male chromosome is XY, and the female chromosome is XX! So some genetic diseases are transmitted to men but not to women!

Because some genetic diseases are inherited by the Y chromosome, they are only transmitted to males and not females.

Because part of people's genes come from their fathers, some wind comes from their mothers, some can only be passed on to boys, and some can only be passed on to girls.

From high school biology, we can conclude that some diseases follow the sex chromosome.

This depends on the genetic inheritance of the person, for example, there are very few women with hair loss.

This is divided into autosomal inheritance and associated genetic diseases, except for the external auditory canal hairiness, there are no other genetic diseases that are transmitted to men and not to women.

According to biological knowledge, it should be related to the type of genetic disease.

Diseases that are transmitted from male to female are inherited from sex chromosomes with Y chromosomes.

1. Depression

Depression is a very common mental illness, depression patients often manifest as: low self-esteem, depression and even pessimism and misanthropy, serious suicide attempts or behaviors, the baby in the pregnant mother's womb has a 10% probability of inheritance from the pregnant mother, because I recommend that the pregnant mother must maintain a good optimistic attitude during pregnancy, so as not to affect the physical and mental health of the fetus.

2. Heart disease

Congenital heart disease is one of the most inherited diseases, if one parent has heart disease at an early age, then the chance of giving birth to a daughter with heart disease or circulatory diseases is greater than that of having a boy, up to a number of times, and if you have had a heart attack before the developmental stage, then you may inherit it.

3. Obesity

Obesity usually does not attract attention, but obesity is also a disease, if obesity exceeds a certain level, it may cause a series of physical diseases, according to the medical school surface, if both parents are obese, the probability of daughter obesity is 78%, if one parent is obese, the probability of daughter obesity is 55%, but the boy Aitong Qiyou Hu is not genetically obese under normal circumstances.

Fourth, dystocia

According to the data, mothers and daughters often have pelvic bones of similar size during pregnancy, and if the mother chooses a caesarean section during pregnancy, then most daughters will also have a caesarean section during pregnancy, and the risk of dystocia will also increase.
