In organisms having double-stranded DNA or RNA, this usually means that the corresponding base pair is also altered. For example, an A:T base pair could be mutated into a G:C base pair or even a T:A base pair.

WebThe four main types of chromosomal mutations are deletion, inversion, duplication, and translocation mutations. Aneuploidy is when a cell has extra or missing chromosomes. Aneuploidy is the result of nondisjunction, which occurs when homologous chromosomes or sister chromatids do not separate during meiosis or mitosis. WebMay 14, 2024 · 18.5: Mutation and Evolution.

WebJun 8, 2024 · Gene duplication, mutation, or other processes can produce new genes and alleles and increase genetic variation. New genetic variation can be created within generations in a population, so a population with rapid reproduction rates will probably have high genetic variation.

WebThe term duplication was coined by Bridges in 1919, and the first duplications were described in Drosophila melanogaster. ADVERTISEMENTS: Duplications may originate in the following four ways: 1.
