148-150.). Mutation is an ongoing process. There are measurable mutation rates and that there can be a genetic variation for mutation rates; mutator strains of bacteria exist. Mutations in the replication or repair machinery of DNA can alter mutation rates. In order for a mutation to be inherited, it must occur in the genetic material of a sex cell. It is likely that most sex cells contain gene mutations of some sort. It is now thought that the frequency of new mutations in humans is about 1 for every 10,000 genes per generation. Mutations. Mutation is a change in DNA, the hereditary material of life. An organism's DNA affects how it looks, how it behaves, and its physiology  all aspects of its life. So a change in an organism's DNA can cause changes in Variation in species can be genetic, environmental or a combination of both. Mutation is a change in a gene or chromosome, and can also be inherited. There are three primary sources of genetic variation, which we will learn more about: 1  Mutations are changes in the DNA. 2  Gene flow is any movement of genes from one population to another and is an important source of genetic variation. 3  Sex can introduce new gene combinations into a population. 1 Mutations are changes in the DNA. 2  A single mutation can have a large effect, but in many cases, evolutionary change is based on the accumulation of many mutations. 3  Gene flow is any movement of genes from one population to another and is an important source of genetic variation. Mutation is a natural process that changes a DNA sequence. And it is more common than you may think. As a cell copies its DNA before dividing, a typo occurs every 100,000 or so nucleotides. That's about 120,000 typos each time one of our cells divides.
