Mutations are added to a gene pool when a mutation (completely random) occurs in a person. They will pass this gene on to their offspring (and so on, and so forth).
Mutations introduce new alleles into the gene pool.
Yes but it could also spread deleterious mutations. It depends on the size of the gene pool.
Mutations in the DNA code can introduce variation into the gene pool of a population.
do it own your own ;p
it changes with every addition
population size, mate selection, gene flow, mutations, natural selection
Gene shuffling means the genetic recombination and mutations of a gene pool of a species where genetic recombination is the mixture of parent alleles that are passed on and the mutations are the random changes in an organisms DNA that are passed on.
*A* gene pool is the collection of all alleles present within a population or species. Alleles are variants for genes. A gene occupies a certain location (or certain locations) on the genome of a species. For many genes in the genome, there are multiple variants upon the basic theme of the gene. The gene pool is an abstract collection, comprised of the totality of all the existing variants for every gene in the genome of a population or species. Each allele in the gene pool has a frequency: the number of individuals out of the entire species or population that carry a copy of that allele. The frequency of an allele within the gene pool is an important measure of evolution. Favorable mutations (variant alleles) will increase their frequency in the gene pool, while detrimental mutations will decrease their frequency.
A gene is a section of a chromosome. So if a gene has a mutation, so does a chromosome.
Three types of gene mutations are substitution, insertion, and deletion. Another gene mutation would be frame shift. All these mutations can cause deformities of the gene.
Darwinian fitness measures the reproductive success of a species. This measures how much of a contribution a specific individual contributes to their species' gene pool, and whether certain gene mutations within an individual will or will not have an overall effect on the gene pool of a species as a whole.

Whoa. Mutations usually cause things to evolve, depending on the gene which is mutated. Mutations are changes in the genetic material of an organism resulting in changes in the gene pool (if the mutated traits are passed on). If the mutated gene is a desirable/advantageous one, then the chances that it willbe passed on to future generations is increased. In this process, which occurs over a period of time, old genes may be lost in the gene pool, resulting in evolution. I don't see how it doesn't cause evolution.

Random mutations of DNA happen and these get inserted into the gene pool as the species breed.
Population Size, Mate Selection, Gene flow between Populations, Mutations and Natural Selection Hope that helps
Gene flow within a population distributes mutations among the individuals. Immigration and emigration transport alleles into and out of a population's gene pool, thus affecting the result of natural selection.
You have this situation backwards. A change in a gene can create a mutation. Mutations do not produce changes in genes. Genes are the cause, mutations are the effect.
The mutations that confer a selective growth advantage to the tumor cell are called “driver” mutations. It has been estimated. A driver gene is one that contains driver gene mutations. But driver genes may also contain passenger gene mutations A typical tumor contains two to eight of these "driver gene" mutations; the remaining mutations are passengers that confer no selective growth advantage.
Gene mutations may have positive or negative effects. Without "positive" gene mutations, a species would not be able to improve itself over time, in order to make it more it more adaptable to its environment. "Negative" gene mutations, by their very nature and definition, tend not to be able to survive in their environment.
A gene getting on the pool. A gene getting off the pool.
Certain gene mutations do not lead to any apparent damage. These mutations are generally the ones in which the resulting amino acid is not changed.
