1. What is Viviparous and eugenics
1. Viviparous: This method of reproduction in which the larvae of humans or certain animals develop within the mother\’s body to a certain stage before leaving the mother\’s body. The fertilized eggs of viviparous animals are generally very small. Fertilization is completed at the upper end of the mother\’s fallopian tube, and then develops into an early embryo and implants in the uterus. After that, it grows on the inner wall of the mother\’s uterus and is connected to the mother through the placenta (Placenta) for absorption. The nutrients and oxygen in the mother\’s blood are transferred to the mother\’s blood and the carbon dioxide and waste products are excreted through the mother\’s body. When the fetus matures, the uterus contracts and expels the baby from the body to form a new independent life.
2. Eugenics: Eugenics originated in Britain, meaning \”healthy inheritance\”. The main purpose is to study how to use effective means to reduce the incidence of fetal defects. Now eugenics has become an important medical technology and national policy. Its main content is to use B-ultrasound, chromosome, and genetic diagnosis technology to control newborns with congenital diseases in order to gradually improve and enhance the genetic quality of the population.
2. What is the purpose of setting up eugenics and postnatal education records
Eugenics The establishment of a good education profile refers to the physical health examination of the couple, as well as health management and guidance before, during and after pregnancy. Through archiving, possible genetic diseases, infectious diseases, malnutrition and other problems can be discovered and prevented in a timely manner, ensuring the health of mothers and infants, reducing disease risks for pregnant women and newborns, and improving birth quality and fertility rate. At the same time, filing can also provide couples with scientific fertility knowledge and health guidance, and promote family harmony and happiness.
3. What is eugenics and eugenics
1. Eugenics and eugenics refer to the comprehensive improvement of people’s health through scientific means The physical, psychological and intellectual qualities of a generation will enable them to better adapt to and cope with various challenges in the future society.
2. Prenatal and postnatal education. The core is to grasp the factors that affect the healthy growth of the child before pregnancy, pregnancy and infancy, including genetic factors, maternal nutrition, maternal emotions, etc.
3. After childbirth, we must pay attention to children\’s dietary health, mental health and intellectual development, so as to build an environment for healthy growth. Prenatal care is not only a personal benefit, but also an important strategy for national development. We will comprehensively improve the quality of the population and inject continuous vitality into the development and growth of the nation.
4. The guiding significance of eugenics
1. Eugenics is a science that specializes in studying human genetics and improving the human race.
2. The purpose of eugenics is to improve the quality of the population, which includes two aspects: one is positive eugenics; the other is negative eugenics
3. Positive eugenics. Eugenics is the promotion of eugenics for individuals with physical and intellectual excellence, that is, the use of molecular biology and cell molecular research to modify and transform genetic materials, control individual development, and make future generations more perfect, truly manipulating and transforming human beings themselves. Purpose.
4. Negative eugenics is to prevent or reduce the birth of individuals with serious hereditary and congenital diseases, that is, to reduce the birth of undesirable individuals. It is the most basic preventive eugenics for human beings and has practical value.
5. Definition of heredity
Heredity generally refers to the similarity of traits between parents and offspring and between individual offspring, indicating that traits can be passed from parents to offspring. This phenomenon is called heredity. But in heredity. In science, it refers to the phenomenon of genetic material being passed from one generation to the next. It is currently known that the existing life on earth mainly uses DNA as genetic material. Heredity is one of the most important factors in eugenics and breeding. In addition to heredity, it determines biological characteristics. Factors include environment and the interaction between environment and genetics.p>
6. What does eugenics mean
1. Eugenics is marriage and family The most important issue is that eugenics is a science that uses the principles of genetics to ensure that offspring have normal viability. Originated from England, meaning \”healthy inheritance\”. The main purpose is to study how to use effective means to reduce the incidence of fetal defects.
2. Eugenics has become an important medical technology and national policy. Its main content is to use B-ultrasound, chromosome, and genetic diagnosis technology to screen and control congenital diseases. Disease newborns, in order to achieve the purpose of gradually improving and improving the genetic quality of the population. Scientific and technological means can be used to ensure fetal health. Our country\’s eugenics work mainly includes the following points: couples with obvious blood relationships are prohibited from marrying, genetic counseling is also provided, and age-appropriate childbearing and prenatal diagnosis are promoted.
