WebbGenetic Variation. Genetic variation is what makes organisms different from one another. A bird is different from a human because of differences in their basic genetic makeup. All genetic variation originally came from the same source, and evolution still relies on that source. Answer and Explanation: WebbGenes are the molecular unit of heredity. In an organism, the gene sequence may occur in one or more forms, and these alternate forms of the same gene are called alleles. Any type of change that is observed in the sequence of these alleles or in the structure of the genes gives rise to genetic variation in the genome of that organism.

WebbMutations are the original source of genetic variation. In humans, recombination contributes to genetic variation by shuffling parental DNA and creating new combinations of variants. Genetic variation is commonly divided into three main forms: Single base-pair substitution, also known as single nucleotide polymorphism (SNP)
