[Answer] The original source of all genetic variation is _____.

Answer: mutation
The original source of all genetic variation is _____.
Genetic variation is the difference in DNA among individuals or the differences between populations. There are multiple sources of genetic variation including mutation and genetic recombination. The mutation is the ultimate source of genetic variation but mechanisms such as sexual reproduction and genetic drift contribute to it as well.
Human genetic variation is the genetic differences in and among populations. There may be multiple variants of any given gene in the human population (alleles) a situation called polymorphism. No two humans are genetically identical. Even monozygotic twins (who develop from one zygote) have infrequent genetic differences due to mutations occurring during development and gene copy-number variation. Differences between individuals even closely related individuals are the key to techniques s…

Mutation is the ultimate source of all genetic variation providing the raw material on which evolutionary forces such as natural selection can act. Mutation can result in many different types of change in sequences. Mutations in genes can have no effect alter the product of a gene or prevent the gene from functioning properly or completely.
Genetics is a branch of biology concerned with the study of genes genetic variation and heredity in organisms.. Though heredity had been observed for millennia Gregor Mendel a scientist and Augustinian friar working in the 19th century was the first to study genetics scientifically. Mendel studied “trait inheritance” patterns in the way traits are handed down from parents to offspring.
