Detailed explanation-1: -Sudden change in one or more gene, or in number or structure of chromosome is called Mutation.
Detailed explanation-2: -Mutation is the sudden change in one or more genes, or in number, or in the structure of chromosomes. A mutation occurs in a DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and harmful chemicals.
Detailed explanation-3: -Mutation is a sudden inheritable change that occurs in the sequence of the nitrogenous base pairs in the DNA. These mutations could be beneficial, harmful or neutral to the organism.
Detailed explanation-4: -This situation is called chromosomal mutation.
Detailed explanation-5: -Mutation is sudden, discontinuous variation in genotype and phenotype of an organism due to change in chromosomes and genes. In addition to recombination, mutation is another phenomenon that leads to variation in DNA. A point mutation is a change of a single base pair in DNA.
