Furthermore, what type of mutation is duplication?
A particular kind of mutation involving the production of one or more copies of any piece of DNA, including sometimes a gene or even an entire chromosome. A duplication is the opposite of a deletion. Duplications have been important in the evolution of the human genome (and the genomes of many other organisms).
How does duplication mutation occur?
Duplications have been important in the evolution of the human genome (and the genomes of many other organisms). Duplications typically arise from an event termed unequal crossing-over (recombination) that occurs between misaligned homologous chromosomes during meiosis (germ cell formation).
What are the 3 types of chromosomal mutations?
The three major single-chromosome mutations: deletion (1), duplication (2) and inversion (3). The two major two-chromosome mutations: insertion (1) and Translocation (2).
