A conditional knockout allows gene deletion in a tissue or time specific manner. This is done by introducing short sequences called loxP sites around the gene.
Image Credit: Main Image: Gene Amplification, also known as gene duplication or chromosomal duplication, is a cellular process in which multiple copies of a gene are produced. The result is an amplification of the phenotype, or expressed trait, associated with the gene.ot all gene amplification has great importance to evolution. Sometimes, the amplified trait dies with the single organism that experiences the gene duplication. This happens when a gene is over expressed and the trait it codes for is expressed to a level that is unhealthy to the organism.
