Genetics is the study of genes, genetic variation, and heredity in living organisms. It is generally considered a field of biology, but intersects frequently with many other life sciences and is strongly linked with the study of information systems.
One of the most important questions posed by climate change is whether species can respond to a changing climate quickly enough to avoid extinction. In order to survive, populations must either be able to adapt to or tolerate the change in environment, or migrate to more suitable conditions.
