Is hemophilia hereditary? How can it be prevented?

There is no way to prevent hemophilia itself, because hemophilia is a hereditary disease, which is a group of bleeding disorders caused by the deficiency of coagulation factors caused by congenital genetic abnormalities, that is, patients are born with hemophilia.

For hemophilia, there is still an alternative, i.e., regular transfusions of blood products containing clotting factors. In the process of hemophilia, the main thing is to prevent malignant bleeding events, and hemophilia patients often have bleeding in the joints and deep muscles.

If the joint bleeds repeatedly, it will lead to joint deformity and affect the patient's daily life, so blood products containing coagulation factors should be transfused regularly to prevent malignant bleeding events.

Hemophilia will be hereditary, because it is a very serious disease, and there is also a high chance of heredity, so we must eat more fresh vegetables and fruits in our daily life, and we must also pay attention to our daily routine, and never let ourselves stay up late, but I think the most important point is that we must do more outdoor sports.

Hemophilia can be hereditary; Under the guidance of a doctor, these drugs should be controlled, more nutrients should be supplemented, daily protection should be paid attention to, and some sharp objects should be avoided.

There is still a lot to know, yes, it will be affected by genetic factors, it may be congenital coagulation factors that have ischemia, there may be nephritis or urinary system infection.

There will be genetic factors, and what I learned is because of chromosome carrying, congenital reasons, and taking some drugs is caused by these reasons.

Yes, partly due to genetic factors, it may also be due to the other partner of the marriage to develop this disease, which may be nephritis or urinary system infection.

We now use A to represent the recessive gene of hemophilia, and the corresponding dominant gene is the dominant gene of hemophilia on the ax chromosome, which is denoted as XA

The hemophilia recessive gene on the X chromosome is denoted as XA

The first scenario is:

xayxaxa

xaxaxaxa

xayxay

Carrier female. Carrier female.

Normal male. Normal male.

That is, the sons born are normal, and the daughters (because the daughter has XA gene, but the phenotype is normal) are carriers.

The second scenario is:

xayxaxa

xaxaxaxa

xayxay

Normal female. Carrier female.

Normal male. Sick male.

That is, 50% of the sons born may have haemophilia A, and 50% of the daughters may be carriers.

The third case.

xayxaxa

xaxaxaxa

xayxay

Carrier female. Sick woman.

Normal male. Sick male.

That is, the probability that the daughter is a hemophilia patient and a carrier is 50%, and the probability of the son born to her is 50%.

The fourth case.

xayxaxa

xaxaxaxa

xayxay

Sick woman. Sick woman.

Sick male. Sick male.

That is, the children born are all hemophiliacs.

Hemophilia is recessive on the X chromosome, and if the male is normal, the daughter is also normal.

There are three types of hemophilia, A, B, C, which type is not specified, and can only be described in their entirety.

The first thing to figure out is the law of heredity, which is common knowledge in high school biology.

In autosomal recessive diseases, the absence of disease does not mean that the disease-causing gene is not carried, so the so-called "severance" cannot be determined without chromosomal testing.

Hemophilia A and B are associated with sex chromosome recessive inheritance, and hemophilia C is autosomal dominant or incomplete recessive inheritance.

1. The genetic law of hemophilia A is as follows: the female transmitter is married to a normal male, and among her children, the boy 1 2 is the patient, and 1 2 is normal; 1 2 in girls is a transmitter and 1 2 is normal.

2 Normal women marry male patients, and all of their children are normal, and all women are transmitters.

The female transmitter is married to a male patient, and among the children of the child is 1 2 normal boys and 1 2 are patients, and 1 2 are patients and 1 2 are transmitters among girls.

Hemophilia A has a genetic pattern, which may be due to a variation on the X chromosome.

2. The inheritance mode of hemophilia B is also associated with recessive inheritance.

3. If it is hemophilia C and the seventh child is not sick, it may be normal, or it may be a carrier of the hemophilia gene; Therefore, the daughter may be normal or a carrier of the hemophilia gene, and if she marries another carrier of the hemophilia C gene, there is still a certain chance that her offspring will be hemophilia.
