A new allele is inserted into the organism
|
Detailed explanation-1: -The whole human family is one species with the same genes. Mutation creates slightly different versions of the same genes, called alleles. These small differences in DNA sequence make every individual unique.
Detailed explanation-2: -New alleles can be formed as a result of mutation, this is the final source. Mutations are permanent changes in the sequences of DNA. It is the first step in creating a new DNA sequence for a specific gene that makes up a new allele.
Detailed explanation-3: -Gene duplication, mutation, or other processes can produce new genes and alleles and increase genetic variation. New genetic variation can be created within generations in a population, so a population with rapid reproduction rates will probably have high genetic variation.
Detailed explanation-4: -Genetic variations can arise from gene variants (also called mutations) or from a normal process in which genetic material is rearranged as a cell is getting ready to divide (known as genetic recombination). Genetic variations that alter gene activity or protein function can introduce different traits in an organism.
