Gene mutation is a heritable molecular level phenomenon in which deletion, addition, shifting or transversion of genes/codon takes place.Mutation prevents our genes to functions properly and causes chromosomal aberrations and ploidy conditions.
Role of gene mutation in organic evolution.
- Mutation leads to origin of new organism that are more complex and diverse to survive the present scenarios.
- Variation that is observed brings us better strains that have advanced molecular machineries to thrive.
- It is slow process and takes years and successive generations to bring its effect.
