There may be multiple variants of any given gene in the human population (alleles), a situation called polymorphism. Genetic variation Without genetic variation, some of the basic mechanisms of evolutionary change cannot operate. Importantly, each of the genomes was assembled without guidance from the first human genome composite. by insects. The mutation is the source of all genetic variation. • - natural selection - meiosis - a need for new traits - mutation What are the 4 factors that affect Photosynthesis? Most biologists appreciate that natural selection filters new mutations (e.g., by eliminating deleterious ones), such that genetic variation in nature is biased.
