August undefined, 2024

Phenotypic variation (due to underlying heritable genetic variation) is a fundamental prerequisite for evolution by natural selection. It is the living organism as a whole that contributes (or not) to the next generation, so natural selection affects the genetic structure of a population indirectly via the contribution of phenotypes. Without phenotypic variation, there would be no evolution by natural selection. WebSpecial Issue Information. Dear Colleagues, Transposable elements (TEs) are mobile DNA sequences that are able to change their chromosomal location. These sequences, which are present in the nuclear genomes of all eukaryotes, were first isolated in consequence of the polymorphisms they induced in hosts. The huge abundance of TEs in plant ...
