How Mutations Occur. A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people. Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes.
Gene mutations can be passed on to future generations and drive natural selection. Gene mutations can be helpful, harmful, or neutral for an organism's survival. [ Only mutations that are helpful in the organism's environment would influence its survival and reproduction.- is the best description of how gene mutations are involved in evolution.A chromosome mutation is an unpredictable change that occurs in a chromosome.These changes are most often brought on by problems that occur during meiosis (division process of gametes) or by mutagens (chemicals, radiation, etc.).Chromosome mutations can result in changes in the number of chromosomes in a cell or changes in the structure of a chromosome.When a new mutation occurs in a somatic cell of a sexually reproducing organism, 50% of the individual's offspring are likely to inherit the mutation. Added 329 days ago|11/9/2022 9:00:34 PM This answer has been confirmed as correct and helpful.Silent mutations occur when the change of a single DNA nucleotide within a protein-coding portion of a gene does not affect the sequence of amino acids that make up the gene's protein. That's possible because proteins are encoded by "triplets" of nucleotides, each responsible for adding a particular amino acid to the protein chain. ...
The incidence of a gene variant (also called a gene mutation) or a genetic disorder is the number of people in a specified group who develop a variant or disorder during a particular time period.

One mutation in the CFTR gene that leads to cystic fibrosis causes translation to end earlier in the gene sequence.
In other cases, the mutation occurs in the fertilized egg shortly after the egg and sperm cells unite. (It is often impossible to tell exactly when a de novo mutation happened.)
