1. Chromosomal mutation
Can refer to any of a number of DNA mutation s which results in a change in the protein encoded by the mutated gene , such as point mutation s, insertion or deletion mutation s ( frameshift mutation s), or nonsense mutation s. More often this refers to mutations involving chromosome s, such as the inversion of part of one chromosome such that the inverted part no longer matches with its homologous pair , a translocation of one part of a chromosome to a different chromosome, deletions of parts of chromosomes, or accidents which happen during the division of the nucleus like the unequal portioning of chromosomes between the daughter cells.
