What is genetic variation?
Genetic variation are variations of genomes between members of species, or between groups of species thriving in different parts of the world as a result of genetic mutation. genetic diversity in a population or species as a result of new gene combinations (example: crossing over), genetic drift, etc. Important in maintaining biodiversity among species.Genetic variation will result in phenotype variation if variation in the order of nucleotides in the DNA sequence results in a difference in the order of amino acids in proteins coded by that DNA sequence, and if the resultant differences in amino acid sequence influence the shape, and thus the function of the enzyme.
