Genetics

• Chemicals, bacteria, viruses, and pollen are examples of genetic material.
• The history of genetics began with the study of these materials.
• Genetics is the branch of Biology that deals with the principles of heredity and variation, coined by William Bateson in 1906 from the Greek word “GEN” meaning to become; to grow.
• Genetics is the science of heredity and variation, including heredity, variation, and the scope of genetics.
• Heredity is the transmission of traits from parents to offspring.
• Variation is the difference from their relatives and ancestors.
• The scope of genetics reaches to the problems of growth, form, and their origin within the members of populations, and on the effects which these diverse genotypes have on the fitness of individuals and of populations as whole entities.
• Genetics is the development and maintenance of his own unique, inherent pattern in dynamic interplay with the environment.
• Genetics is the ability to transfer these systems to the other generations for continued existence.
• Genetics is the ability of living forms as a whole to improve through breeding and genetic engineering.
• Genetics is closely associated with other sciences such as morphology, taxonomy, embryology, cytology, biochemistry, ecology, evolution, bacteriology, statistics.
• Genetics is the improvement of agricultural plants through selective breeding or genetic engineering, including increasing yield, improving disease resistance, ameliorating insect resistance, and synthesizing plants with multiple qualities.
• Genetics is the improvement of animals for disease resistance and utility.
• Genetics is the improvement of human welfare through the development of improved types of cereals, vegetables, fruits, ornamental plants, medicinal & aromatic plants, spices etc.
• Genetics is the improvement of human welfare through applications in agriculture, medicine, and industry.
• Genetics is the improvement of human welfare through applications in agriculture, including selective breeding and genetic engineering, to develop improved types of cereals, vegetables, fruits, ornamental plants, medicinal & aromatic plants, spices etc.
• Genetics is the improvement of human welfare through applications in medicine, including the development of genetic tests and therapies.
• Genetics is the improvement of human welfare through applications in industry, including the development of genetically modified organisms.
• Recombinant DNA technology/ genetic engineering is used in the production of GMOs.
• Modern studies on genes include oncogenes, which target oncogenes (genetic mutations that cause cancer), and antibody diversity, which involves designing antibodies that specifically target a certain antigen, such as found on cancer cells.
• Eugenics aims to improve the hereditary constitution through genetic surgery or genetic engineering, and can involve parthenogenesis to induce females bearing desirable genetic constitutions to lay diploid eggs which do not have to be fertilized.
• Homeotic genes are responsible for regulating the development of an organism’s organs and specific portions of the body during its embryonic stages, or while the organism is developing in an egg or womb.
• Negative eugenics involves the attempt to decrease the frequency of harmful genes.
• This cell line could be used to create genetically engineered cattle that produce BLG-free hypoallergenic milk.
• Pedigree analysis is used to analyze the pattern of transmission of a trait from generation to the next.
• Statistics is a basic tool in any genetic study.
• DNA fingerprinting is used in paternal cases/ child disputes as well as in forensic science.
• Planned experimental study is a method used in genetic studies that involves using useful organisms with short life cycles, large number of offspring, and easy handling.
• Genetic counselling includes talking to parents of children with genetic disorders about the prognosis and possible treatment of the disorder, predicting the possible outcome of matings involving carriers of harmful genes, giving counsel about available options, and using pedigrees as aids.
• Twin study proves that not all traits can be altered by environment.
• Genome editing could help create BLG-free milk, but such approaches will need to successfully undergo several more steps before hypoallergenic milk can come to market.
• Karyotype analysis is a test to examine chromosomes in a sample of cells.
• Positive eugenics involves the attempt to increase the frequency of beneficial genes.
• Euthenic refers to the control of the environment, especially with a view to improving the health and living standards of the human race.
• Antigen is any substance that causes your immune system to produce antibodies against it.
• Behavioral genetics helps researchers understand drivers of human behavior by examining the degree of influence these existing genetic traits.
• Antibody is a blood protein produced in response to and counteracting a specific antigen.
• Genetic disorders and cancers can be treated using genetics.
