11.6 How Asexual Prokaryotes Achieve Genetic Diversity

WebbThere are three primary sources of new genetic variation: Mutations are changes in the information contained in genetic material. (For most of life, this means a change in the sequence of DNA.) A single mutation can have a large effect, but in many cases, evolutionary change is based on the accumulation of many mutations with small effects. WebbBiodiversity or biological diversity is the variety and variability of life on Earth.Biodiversity is a measure of variation at the genetic (genetic variability), species (species diversity), and ecosystem (ecosystem diversity) level.
