Mutations are the result of DNA replication errors that are not corrected during transcription. As DNA replicates and recombines during mitosis, the possiblity of errors increases. Once an error occurs it is replicated everytime the cell goes through mitosis. These mutations affect bases, base pairs and codons.

In meiosis, errors occur in the same manner, but are passed on to future generations as sperm and egg combine. Probability plays into the possibility of being a carrier or actually having the genetic  mutation.

DNA can be affected, or altered, due to a variety of reasons such as radiation, illness, medication and environmental carcinogens. Alterations have the ability to effect protein production and cell regulation. Mutations are always the result of loss of genetic information. There are mutations that don't harm the individual, but the majority are unfavorable. The list of genetric diseases is quite lengthy.

The three main types of mutations, seen in DNA replication, are deletion, substitution and insertion. Deletions are usually lethal when they are homozygous.
