In regards to homopolymeric tract variation, Wilson et al. suggested that generation of genetic diversity occurs in specific, permissive environments such as the avian intestine where C. jejuni is a commensal organism [51].
Our results support the fact that human interaction networks have shaped the genetic architecture of domestic animals while harsh environments such as deserts tend to limit human interactions and hence gene flow among domesticates.
Genetic correlations in natural populations of bank voles should be stronger than those estimated here, since genetic correlations are typically weaker in good environments such as laboratory conditions [ 22, 45].
Genetic diversity may be reduced due to directional selection in extreme environments (such as very low temperatures or salinity), or due to bottleneck effects such as those induced by high fishing pressure (Frankham et al. 2002).
By contrast, stochastic environments, such as high-altitude habitats, may select for outcrossing, leading to high levels of genetic variability and favoring population persistence [ 81].
The global expansion of genetic and genomic research highlights our need to understand informed consent practices for studies in ethnically diverse cultural environments such as Africa.
Controlled environments, such as jails, are ideal.
For example, he says, genetic pathways from organisms that can break down environmental pollutants could be engineered into bacteria that could survive in harsh and contaminated environments, such as acidic ponds, and then used to clean up those areas.
Avoid dusty environments, such as construction sites.
This suggested that shared genetic vulnerability or common elements of social environment, such as poverty and early exposure to violence, were at least partially responsible for violent behavior.
