Factors influencing eugenics, both genetic and non genetic

Eugenics is affected by genetic and environmental factors The incidence of important defects in the general population is about 2%, which can be body surface deformities or visceral malformations. It can occur due to genetic factors (about 25%), environmental factors such as exposure to chemicals, drugs, radioactive materials or various infections (about 10%), or a combination of environment and heredity (65%). Therefore, in order to achieve eugenics, it is necessary to pay attention to both aspects of health care before planning pregnancy:

On the one hand, it is necessary to do a good job in genetic counseling and control the adverse effects of genetic factors on the fetus as much as possible; On the other hand, it is necessary to pay attention to environmental protection, including the general environment in which the mother is located and the small environment in which the fetus grows in the mother, and avoid the influence of adverse environmental factors as much as possible. The environmental factors affecting the development of the embryo include three aspects: (1) the external environment in which the mother is located, which is the farthest and most complex external environment from the embryo, and most of the teratogenic factors are in this environment; (2) The environment of the mother itself is the environment in which the embryo grows and develops, including the nutritional status of the mother, the type of metabolism, whether it is diseased, etc.; (3) The microenvironment in which the embryo is located, including fetal membranes, embryos, amniotic fluid, etc.

This is the microenvironment that acts directly on the embryo. Some teratogenic factors in the external environment can directly act on the embryo through the internal environment and microenvironment, and some affect and change the internal environment and microenvironment and indirectly act on the embryo. The same is true for changes in the mother's internal environment.

Genetic factors are inherited diseases in the family, including both parents.

Intangible cultural heritage factors are the factors that cause the fetus to develop normally due to external factors. For example: smoking, drinking, staying up late, malnutrition, etc.

What are you going to ask.

First of all, we must avoid these problems, if we can't avoid them, we should minimize the consequences of these factors, eugenics, we all hope that the child can be healthy, take folic acid during pregnancy, start taking nutrition in the first trimester, vitamins and the like, blood and iron supplements, multi-dimensional words have eugenics are better, you can refer to it!

The latest medical research has found that children have too much opioid content in the brain, so they often have symptoms of loneliness, numbness and emotional communication disorders, so it is inferred that there is a problem with the neurotransmitters in the brain of patients with autism. So far, there are many theories, but there is no clear conclusion on what causes autism in children.

Heredity is a common phenomenon in the biological world, and all organisms produce offspring according to their own patterns in the process of inheritance, so that every individual who is replanted inherits the basic characteristics of the previous generation. Heredity is the basic condition for the continuation of human beings and various organisms from generation to generation, and is an innate factor that determines the healthy development and change of the human body. Therefore, understanding the genetic material of the human body, grasping the laws of heredity, continuing and developing the good genes, "modifying" the bad genes, blocking the continuation of genetic diseases, and improving the quality of the population have a bearing on the prosperity of the Chinese nation and the smooth development of the cause of the four modernizations.

Since the beginning of the 20th century, Morgan et al. have proposed the "chromosome-gene" theory. After the concretization of Mendel's hypothetical genetic factors on chromosomes, in the 40s of the 20th century, with the development of physics, chemistry and biology, the application of new technologies slowed down, and it was fully proved that chromosomes are composed of nucleic acids and proteins, and the genetic material that constitutes genes is nucleic acids. Nucleoacids are divided into two categories: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

DNA is a carrier that stores genetic information (genetic code), has relative stability, can accurately self-replicate, maintain genetic continuity between parents and offspring, can guide protein synthesis, tap metabolic processes and trait development, and can also produce genetic variation under specific conditions. However, the transmission of genetic information from the chromosomes of the nucleus to the cytoplasm outside the nucleus is also closely related to RNA. Genetic information is first transcribed from DNA to RNA, which then carries the genetic information outside the nucleus to proteins.

The inheritance of normal traits in the human body includes the inheritance of more than 20 kinds of pregnancy traits in terms of gender, body surface traits, physiological and biochemical characteristics, and physical fitness. 

I can be sure that many people who are preparing to become parents have a certain understanding of the phrase "genetic disease and eugenics" and what it contains or some examples, because many real unfortunate cases are really shocking. Then I will only make a brief description of genetic diseases and eugenics here, mainly to attract your attention.

Genetic diseases are diseases that are caused by changes in genetic material or controlled by disease-causing genes. Genetic disorders are diseases that are determined wholly or partly by genetic factors, often congenital or acquired. Such as congenital stupidity, polydactyly (toe), congenital deaf-mute, hemophilia, etc., these genetic diseases are completely determined by genetic factors, and the onset of the disease occurs after a certain period of time, and it takes several years, more than ten years or even decades to appear before obvious symptoms can appear when there are disadvantages.

So, can genetic diseases be **? Previously, it was thought that genetic diseases were incurable. However, in recent years, with the development of modern medicine, medical geneticists have clarified the pathogenesis of some genetic diseases in the study of genetic diseases, thus providing a certain basis for the prevention and prevention of genetic diseases, and new first-class measures have made great contributions to eugenics.

The term "eugenics" was first coined by the British human geneticist Galton in 1883, and its original meaning was "healthy heredity". He advocated that the spread of undesirable genetic qualities and the birth of inferior individuals should be reduced through selective marriage, so as to achieve the goal of gradually improving and enhancing the genetic qualities of the population. In layman's terms, the "birth" of eugenics refers to birth, "excellent" is excellent or excellent, eugenics is to give birth to superiority, that is, the use of genetic principles and a series of measures to make the offspring healthy and intelligent.

At present, China's eugenics work mainly includes the following points: prohibiting marriage between close relatives, conducting genetic counseling, and advocating age-appropriate childbearing and prenatal diagnosis.

I conclude: or the old saying "know yourself and know the other side to win a hundred battles", now science and technology are more and more developed, the research of life science is also advancing day by day, as long as we know what is a genetic disease, we will be able to follow the vine to study how to prevent genetic diseases, in reality, many have become a reality, so that eugenics is more fully prepared. I hope the above knowledge can help you understand "genetic diseases and eugenics".
