NEET BIOLOGY

Detailed explanation-1: -Genetic information is passed from generation to generation through inherited units of chemical information (in most cases, genes). Organisms produce other similar organisms through sexual reproduction, which allows the line of genetic material to be maintained and generations to be linked.

Detailed explanation-2: -Selective Breeding Through selective breeding, humans choose organisms with wanted characteristics to produce the next generation. This takes advantage of natural variation among organisms and passes wanted traits to offspring.

Detailed explanation-3: -Recombinant DNA technology is the joining together of DNA molecules from two different species. The recombined DNA molecule is inserted into a host organism to produce new genetic combinations that are of value to science, medicine, agriculture, and industry.

Detailed explanation-4: -Gene therapy is used to correct defective genes in order to cure a disease or help your body better fight disease. Researchers are investigating several ways to do this, including: Replacing mutated genes. Some cells become diseased because certain genes work incorrectly or no longer work at all.
