1. What is eugenics Science
1. Eugenics is the science of using the principles and methods of genetics to improve human genetic quality, prevent birth defects, and improve population quality.
2. Simply put, eugenics means taking certain measures to ensure that future generations have good physique and excellent genetic qualities. The main tasks of eugenics have two aspects: First, to improve knowledge about the genetic nature of different human characteristics, determine the advantages and disadvantages of these characteristics and decide on trade-offs, that is, on the basis of human genetics, elucidate the genetic control of certain human characteristics and its inheritance method, and then judge its advantages and disadvantages in future society or the pros and cons of human evolution from the perspectives of medicine, genetics and sociology; the second is to propose measures to improve the genetic quality of future generations, that is, in the first Based on the tasks, a plan to increase or decrease the expression frequency of a certain gene is formulated. Genetic counseling, prenatal diagnosis and elective abortion are the three main means to accomplish the above tasks. Further reading: Scope of modern eugenics The development of eugenics can be divided into three stages.
2. How to classify eugenics
1. Eugenics Classification: Eugenics is a comprehensive and multi-disciplinary developing science, which can currently be divided into the following fields:
2. ①Basic Eugenics. Study from the aspects of biology and basic medicine what factors can cause birth defects, how they work, and how to prevent their effects.Used to achieve eugenic purposes. Epidemiological surveys on the types, distribution and incidence of hereditary and congenital diseases across the country are very meaningful basic eugenics research and can provide reliable basic information for eugenics policies, eugenics legislation and eugenics technical measures.
3. ②Social eugenics. Study eugenics issues from the aspects of social sciences and social movements. The purpose is to promote eugenics legislation, implement eugenics policies, carry out eugenics publicity and education, and popularize and socialize eugenics work, thereby achieving the purpose of improving the quality of the population.
4. ③Clinical eugenics. A study of medical practices related to eugenics. It can be divided into two major branches. One is preventive eugenics, also known as negative eugenics or negative eugenics. It mainly studies how to avoid the birth of poor offspring, prevent diseases, and eliminate poor offspring. The other branch is evolutionary eugenics, also known as positive eugenics or positive eugenics. It mainly studies how to give birth to excellent offspring and studies eugenics from the perspective of promoting better innate qualities of newborns. Both have the same purpose, which is to reduce unfavorable genetic factors and increase favorable genetic factors to improve population quality.
3. What is eugenics check
In recent years, people have paid more attention to More and more attention is paid to eugenics and postnatal care. The examination items for eugenics and postnatal care include: blood routine, urine routine, liver function test, reproductive system examination, a full set of deformities (rubella, toxoplasma, cytomegalovirus), and six endocrine items (luteal survival hormone, follicle stimulating hormone and other indicators), ABO hemolysis; in addition, if you have a genetic history, targeted examinations are also required.
4. What is a eugenics consultation room
Eugenics consultation is eugenics It is an important part of the work, which involves doctors or other professionals providing information about the cause, inheritance, diagnosis, prognosis, prevention and treatment of the disease to patients with genetic diseases or congenital malformations or their relatives, as well as the risk of recurrence of the disease in relatives\’ children. Answer questions such as rates, etc., and provide suggestions and guidance on issues such as marriage and childbirth for patients and their relatives, so as to control certain adverse factors and prevent fetal development defects to achieve eugenic purposes.
5. What does eugenic preferential treatment mean
1. Eugenic preferential treatment It refers to policy measures taken to promote good genetic inheritance and optimize population structure. This concept originates from the fields of reproductive policy and population management. The purpose of eugenic preferential treatment is to encourage outstanding talents to have children and improve the quality of the population and the quality of their genes.
2. In some countries, the government may encourage high-quality people to have children and take care of their children through various means, such as providing economic incentives, educational resources, employment opportunities, etc.
3. This policy aims to cultivate a healthier, smarter and competitive next generation.
6. The genetic significance of mitosis
1. Chromosomes in the nucleus Accurate replication and division lay the foundation for the genetic composition of the two daughter cells to be exactly the same as that of the mother cell; the two sister chromatids produced by chromosome replication are allocated to the two daughter cells respectively, and the daughter cells have the same number and composition of chromosomes as the mother cell .
2. Maintain the normal growth and development of individual organisms; ensure the continuity and stability of species.
