∙ 15y agoCloning vectors are used to increase the number of copies of the cloned gene or to amplify a foreign gene. Expression vectors are used to increase the expression of the foreign gene product.
it stops gene flow
Reproductive isolation limits gene flow between populations, allowing genetic differences to accumulate over time. This can lead to the development of new species, increasing biodiversity within an ecosystem.
Because they produce with whomever they want which gives them more varieties in a gene pool

gene flow
A proto-oncogene can be converted into an oncogene through mechanisms such as gene amplification, chromosomal rearrangements, or altered regulation of gene expression without changes in its coding sequence. These alterations can lead to increased expression or activity of the proto-oncogene, resulting in uncontrolled cell growth and division characteristic of cancer cells.
Gene therapy is a promising medical approach that involves introducing genetic material into a person's cells to treat or prevent a disease.
Geographic isolation Low geneflow.
In a transgenic organism with extra gene copies, there is typically an increase in the production of the corresponding RNA due to the additional gene copies being transcribed. This can lead to an elevated expression level of the gene's product, which could result in observable phenotypic changes in the organism.
An example of a gene is the BRCA1 gene, which is known for its role in hereditary breast and ovarian cancer. This gene provides instructions for making a protein that helps repair damaged DNA and maintain the stability of the cell's genetic material. Mutations in the BRCA1 gene can increase the risk of developing certain types of cancer.
