Genetic variation refers to variation (change or difference) of the gene among the members of the same species or individuals.<\/strong><\/p>\n\n\n\n

Genotype is the total sum of genetic determinants carried by a cell that is transmitted from generation to generation. Genotype is determined by the genetic information contained in the entire DNA content of the genome in the chromosome.<\/p>\n\n\n\n

Genes carry instructions that are used for building protein. Differences in DNA sequence or gene between individuals are also known as genetic variations, and each variation of a gene is called an allele<\/a>.<\/p>\n\n\n\n

Genetic variation occurs in entire species, known as genetic diversity. Genetic variation is essential for the natural selection process because natural selection can only decrease or increase the allelic frequency already present in the population.<\/p>\n\n\n\n

Genetic variation plays an advantageous role in the population because it favors some individuals to adapt to the environment. Mutation, gene flow, sexual reproduction, random mating between organisms, random fertilization, and crossing over are the main cause of genetic variation. Genetic variation along with environmental variation causes phenotypic variation in a population. An example of phenotypic variation is the height of a plant.<\/p>\n\n\n\n
