WebJan 25, 2024 · A Mutation is defined as a sudden, random and directionless change in the genetic sequence. As we know the different alleles present in different gene pools cause phenotypic variations like these. Alleles are the mutated copies of a single gene responsible for the particular character. WebJan 13, 2024 · A missense mutation occurs when there is a mistake in the DNA code and one of the DNA base pairs is changed, for example, A is swapped for C. This single change means that the DNA now encodes for a different amino acid, known as a substitution. Sometimes a change in the amino acid has no effect on the resulting protein's function at …

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. Primary structural change of chromosomes 2. Disturbances in the crossing over process (unequal crossing over) ADVERTISEMENTS: 3. WebDuplication is a type of chromosomal mutation that occurs when a section of a chromosome is repeated. This causes the two homologous chromosomes to have different amounts of genetic material.
