Genetic variation

Genetic variation is the difference in DNA among individuals[1] or the differences between populations among the same species.[2] The multiple sources of genetic variation include mutation and genetic recombination.[3] Mutations are the ultimate sources of genetic variation, but other mechanisms, such as genetic drift, contribute to it, as well.[2]

Parents have similar gene coding in this specific situation where they reproduce and variation in the offspring is seen. Offspring containing the variation also reproduce and passes down traits to their offspring.
