How is evolution defined in genetic terms
WebEvolutionary biologists use the word fitness to describe how good a particular genotype is at leaving offspring in the next generation relative to other genotypes. So if brown beetles consistently leave more offspring than green beetles because of their color, you'd say that the brown beetles had a higher fitness. Web- Evolution involves change over time on a population What are the sources of genetic variation? - Mutation, reproduction, and gene transfer - Mutation , reproduction , and gene transfer What determines the number of phenotypes for a given trait? - depends on how many genes control the trait - depends on how many genes control the trait

WebSomatic evolution is the accumulation of mutations and epimutations in somatic cells (the cells of a body, as opposed to germ plasm and stem cells) during a lifetime, and the effects of those mutations and epimutations on the fitness of those cells.
