A mutation is any change to a strand of DNA which is passed on to an organism's offspring.
DNA mutations are caused usually by chemical interactions or radiation (natural and manmade), and most are harmless.
The only ones which cause serious defects (that I know of) are changes to sperm or egg cells, stem cells (which might ultimately be responsible for the DNA and development of an entire region of your anatomy) and changes which cause cancer.
If a fetus or embryo is exposed to intense radiation, they will be at high-risk for harmful genetic mutations because their body is still developing, whereas an adult will be relatively immune since most of the time if a strand of DNA in a cell is damaged the cell just dies and is replaced.
Genetic mutation is when the base pairs of DNA are changed. There are three basic types of mutation; deletion, addition, and substitution. Deletion is when a base pair is removed from the strand of DNA. Addition is when an extra base pair is added to the strand of DNA. And substitution is when a base pair is traded out with a different base pair.
Mutation is generally accepted by the scientific community as the mechanism upon which natural selection acts, providing the advantageous new traits that survive and multiply in offspring or disadvantageous traits that die out with weaker organisms.

A gene mutation is a permanent change in the DNA sequence, that makes up a gene. Mutations range in size, from a single DNA building block (DNA base), to a large segment of a chromosome.

I think I am the product of genetic mutation What should I do?
If you think you have a large genetic mutation, consult your doctor.
What is the difference between crossover and mutation in genetic algorithm?
mutation means change in genetic structure..where as crossover means interchanging the genetic structure of two or more chromosomes..
A change in the genetic material of a cell is called?
Cancer- certain mutations (changes) in a cell's genetic material may cause that cell to reproduce with out control.
Which mutation results in a single missing letter in the genetic code?
frameshift mutation: deletion
What is the change of a cell's genetic information called?
A mutation.
A mistake made during copying of genetic information is called a?
A mistake made during copying of genetic information is called a
I think I am the product of genetic mutation What should I do?
If you think you have a large genetic mutation, consult your doctor.
What do you call a genetic change that is permanent?
it is a mutation
A change in a population gene pool due to a chance event?
This is known as genetic drift, where allele frequencies in a population change due to random sampling. It is more pronounced in smaller populations and can lead to the loss of genetic variation.
What are genetic mutation and natural selection?
Together, genetic mutation and natural selection determine in what 'direction' evolution proceeds.
What is caused by genetic mutation?
cancer
What is the difference between crossover and mutation in genetic algorithm?
mutation means change in genetic structure..where as crossover means interchanging the genetic structure of two or more chromosomes..
What can a genetic mutation cause?
A genetic mutation can cause a variation, which may be harmless, or may be harmful, depending on where on the DNA molecule it occurs.
What is a mutation operator?
A mutation operator is a function or process that introduces changes in the genetic material (DNA) of an organism, leading to genetic variations or mutations. In the context of evolutionary computation and genetic algorithms, mutation operators are used to explore new solutions by altering the genetic information of individuals in the population.
What do you call a change in the genetic code?
A change in the genetic code is called a mutation. This can result from errors during DNA replication, exposure to mutagens such as chemicals or radiation, or spontaneous changes. Mutations can have various effects on an organism, ranging from no consequences to causing genetic disorders.
What is one source of genetic variations in sexual reproduction?
It is through mutation.
The original source of genetic variation that serves as the raw material for natural selection is what?
Generally, mutation.
