Molecular breeding is the application of molecular biology tools, often in plant breeding [1] [2] and animal breeding. [3] [4] In the broad sense, molecular breeding can be defined as the use of genetic manipulation performed at the level of DNA to improve traits of interest in plants and animals, and it may also include genetic engineering or gene manipulation, molecular marker-assisted ...
Genetic testing, also known as DNA testing, is used to identify changes in DNA sequence or chromosome structure. Genetic testing can also include measuring the results of genetic changes, such as RNA analysis as an output of gene expression , or through biochemical analysis to measure specific protein output.

For known DNA sequences, restriction enzymes that cut the DNA on either side of the gene can be used. Gel electrophoresis then sorts the fragments according to length. [20] Some gels can separate sequences that differ by a single base-pair. The DNA can be visualised by staining it with ethidium bromide and photographing under UV light.
Genetic analysis is the overall process of studying and researching in fields of science that involve genetics and molecular biology.There are a number of applications that are developed from this research, and these are also considered parts of the process.

It is based on the natural DNA-repair mechanism of Homology Directed Repair (HDR), including Homologous Recombination. Gene targeting can be used to make a range of sizes of DNA edits, from larger DNA edits such as inserting entire new genes into an organism, through to much smaller changes to the existing DNA such as a single base-pair change.
Marker assisted selection or marker aided selection (MAS) is an indirect selection process where a trait of interest is selected based on a marker (morphological, biochemical or DNA/RNA variation) linked to a trait of interest (e.g. productivity, disease resistance, abiotic stress tolerance, and quality), rather than on the trait itself.
