Deletions... 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.
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. WebDuplication mutations occur when a segment of a chromosome is copied and inserted into the homologous chromosome, resulting in extra genetic material. An example of a human disorder caused by duplication mutation is Charcot-Marie-Tooth disease type 1A.
