Genetic pollution is a term for uncontrolled [1] [2] gene flow into wild populations. It is defined as "the dispersal of contaminated altered genes from genetically engineered organisms to natural organisms, esp. by cross-pollination", [3] but has come to be used in some broader ways.

Genetic erosion in agricultural and livestock is the loss of biological genetic diversity – including the loss of individual genes, and the loss of particular recombinants of genes (or gene complexes) – such as those manifested in locally adapted landraces of domesticated animals or plants that have become adapted to the natural environment in which they originated.
Countries are expected to reach a deal at this month's U.N. COP16 nature summit on how the world uses and pays for genetic information extracted from nature, according to negotiators. Experts ...
Genetic rescue has the possibility of actually lowering the fitness of a population by swamping the population or increasing rare deleterious alleles. [10] This instance may simply be termed genetic pollution instead of being referred to genetic rescue. Rescue may also only be a short-term solution, as shown by the case of the Isle Royale Wolves.
Evolution is the change in the heritable characteristics of biological populations over successive generations. [1] [2] It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations.

This is a glossary of environmental science. Environmental science is the study of interactions among physical, chemical, and biological components of the environment. Environmental science provides an integrated, quantitative, and interdisciplinary approach to the study of environmental systems.
A cryptic species is a species that humans cannot tell is different without the use of genetics. Moreover, gene flow between hybrid and wild populations can result in loss of genetic diversity via genetic pollution, assortative mating and outbreeding.
