|
|
to bring about an exchange of genetic materials between two parent plants/animals/microorganisms to produce offspring having desired traits.
|
Selective breeding
|
|
|
various scientific techniques used to produce specific desired traits in plants, animals or microorganisms through the use of genetic knowledge.
|
Modern biotechnology
|
|
|
involves direct modification of DNA using techniques like gene splicing and recombinant DNA.
|
New Biotechnology/ Genetic Engineering
|
|
|
an organism whose genetic material has been altered using techniques in genetics generally known as recombinant DNA technology.
|
Genetically Modified Organism (GMO)
|
|
|
combines DNA molecules from different sources into one molecule in a test tube.
|
Recombinant DNA technology
|
|
|
Expression of certain traits, the phenotype of the organism, or the proteins it produces, can be altered through the modification of its genes
|
Recombinant DNA technology
|
|
|
Genes that directly express desired traits, such as agronomic performance, are identified _____ ______
|
More readily
|
|
|
provides the potential to select the exact characteristics desired, but it also enables us to transfer genes for desired traits more precisely.
