How does preserving genetic material work
WebJun 24, 2024 · Genetic engineering is the process of manipulating or altering the genetic makeup of an organism — be it an animal, plant or a bacterium. This can be achieved by using biotechnology to remove a gene from one organism and inserting it into another, giving it the ability to express the trait encoded by that gene. WebGenetic variation, as well as changes in the environment, cause characteristics of organisms to change over time. This process of natural selection leads to the evolution of new species.

It fosters the exchange of genes between different populations. It restricts the gene pool by chance events such as floods or other catastrophic events. It allows the frequency of a recessive allele in a population to be predicted under certain conditions.
