What is genetics?

Genetics biology is studying heredity / Variations (Variation) of inheritance and fauna under the branch. The fundamental achievements of Gregor John Mendel in the study of heredity have now been incorporated into genetics.

Introduction of genetics

All creatures, whether animals or plants are true models of their ancestors. In scientific language. Certain factors are specifically studied in genetics:

  • The first factor is inheritance. The inheritance of an organism is the chemical information that germ cells receive from their parents (ancestors or parents). For example, The way a creature grows determines its inheritance.
  • The second factor is the distinction we find or can find in a creature and its children. Almost all creatures show signs of their parents or sometimes Baba, Dadi, or their previous generation. It is also possible that some of its features are completely new. This kind of change or difference has many causes.

It also depends on the growth of the organisms and their environment. The environment of the beings is very complex; This includes the organization of the organism, the strength, and the organism as well as the perception of the organism.

The scientist examines all of these factors in one sentence. We can say that genetics is the science under which genetics and their ancestors have relationships and reasons, reasons for their formation and development. The possibilities are being explored.

In 1911 (1911) Johannesen differentiated between the external characteristics of organisms and genotypes. The external properties of organisms change as they grow, such as the correct physical differentiation of organisms in the embryo, in infancy, in puberty, and old age. On the contrary, their ancestral characteristics or properties are stable and immutable. The natural properties of an organism and the interactions of the environment lead to its growth and development. Presumable characteristics thus determine how organisms react to the norm (norm reaction), ie their reaction to the environment. These types of responses create the phenotype of organisms.

Genetic elements are used in agricultural science concerning plant size, production, disease prevention, and pet breed enhancement, etc. With the help of genetic elements, the study of evolution, embryology, and other related sciences are facilitated. This science has resolved many illusions related to symptoms and diseases. This science has raised many problems in twinning and eugenics. In some ways, human society has benefited from many important advances in population genetics.

T.H. Routing (1886–1945) and his colleagues showed that certain genes that are known from hereditary experiments (crossbreeding experiments) are only present on certain chromosomes (chromosomes) via microsystems. He also explained that these genes are arranged in a defined order within the chromosomes, making it possible to create a genetic map.

 These people took several pictures of the Kadali fly’s gene, Drosophila. Professor Müller has made a very important contribution in this direction. He led innovative scientific research through unprecedented experiments in the field of mutation. Many artificial mutation methods have surprising improvements in domestic animals and agricultural breeds. All of this is due to genetics, which has proven to be the maximum beneficiary of human well-being.

Many scientists believe that genetic testing of humans is not an easy task. The reason for this is given that the birth of a human child takes about 10 months and takes at least 20 years to become a full adult. Therefore, human genetic testing is complicated since it takes 20.22 years to study a single generation. A man usually only has one child, which makes learning difficult. Despite these difficulties, studying the external structure of the human body, diseases, their symptoms, and causes, etc. is easy. Archibald Garrod (1858–1937) provided the basis for the production of humans for the development of humans. Archibald Garrod (1858–1937), but there was no detailed study on the subject before 1980. Relationship to the gene.
