Further explanation
Genetic variation is the variation that occurs in the genome of an organism in either nucleotide bases, genes or chromosomes. Genetic variation at the elementary level is indicated by differences in the sequence of nucleotide bases.
Half of the genes that encode enzymes in insects and plants may be polymorphic, whereas polymorphisms are less common among vertebrates.
Sources of genetic variation include mutation, migration and recombination. The parameters used to analyze genetic variation are haplotype diversity, nucleotide diversity and genetic distance. Analysis of genetic variation can be done with molecular markers. One of the molecular markers that can be used to see genetic variation is the cytochrome oxidase subunit 1 or commonly referred to as the CO1 gene
In the end, genetic variation is caused by variations in base sequences in nucleotides in genes. New technology now allows scientists to directly sort DNA that has identified more genetic variation than previously detected by protein electrophoresis. DNA examination has shown genetic variation in both the coding region and in the non-coding intron region of the gene.
Genetic variations will produce phenotypic variations if variations in the nucleotide sequence in the DNA sequence produce differences in the amino acid sequence in the protein encoded by that DNA sequence, and if the differences produced in the amino acid sequence affect the shape, and thus function of the enzyme.
