What are sources of variation in a population?
For a given population, there are three sources of variation: mutation, recombination, and immigration of genes. However, recombination by itself does not produce variation unless alleles are segregating already at different loci; otherwise there is nothing to recombine.Click to see full answer.

For a given population, there are three sources of variation: mutation, recombination, and immigration of genes. However, recombination by itself does not produce variation unless alleles are segregating already at different loci; otherwise there is nothing to recombine.Click to see full answer. Also know, what are the main sources of genetic variation in a population?Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism’s offspring).Furthermore, what are three sources of genetic variation in a population? There are three sources of genetic variation: mutation, gene flow, and sexual reproduction. A mutation is simply a change in the DNA. Mutations themselves are not very common and are usually harmful to a population. Because of this, mutations are usually selected against through evolutionary processes. Regarding this, what is the source of variation in a population quizlet? Natural selection acts on the variation in populations. Mutations, gene flow, and genetic recombination are all sources of genetic variation in populations. These processes generate the variation on which natural selection acts.How is variation maintained in a population?Genetic variation is maintained through crossover during meiosis, in the formation of games, sperm or ova. Genetic variation occurs through mutation or intercellular gene transfer between individuals due to accidental genetic mutation, such as from causes that may be chemical, mechanical, or from radiation.
