Artificial selection Adaptation Misconceptions about natural selection Coevolution A case study of coevolution: squirrels, birds, and the pinecones they love Gene flow is the exchange of alleles between two or more populations. For this reason it is sometimes referred to as allele flow or gene migration. While migrating animals often carry new alleles from one population to another, they must interbreed with the new population for gene flow to occur.

WebThe process of introducing a gene into a host organism—typically via a plasmid—is known as transformation. It is a crucial stage in the genetic engineering process because it enables the introduction of a new gene into an organism. Flow Chart for Plasmid-Based DNA Recombinant Technologies. 1. WebA gene is a segment of DNA in an organism's genome that encodes a functional RNA (such as rRNA, tRNA, etc.) or protein product (enzymes, tubulin, etc.). A generic gene contains elements encoding regulatory regions and a region encoding a transcribed unit.

WebGene flow is any movement of genetic material from one population to another (e.g., through migration) and is an important source of genetic variation. Sex can introduce new gene combinations into a population. This genetic shuffling is another important source of genetic variation. Genetic shuffling is a source of variation.
