A chromosome mutation is an unpredictable change that occurs in a chromosome.These changes are most often brought on by problems that occur during meiosis (division process of gametes) or by mutagens (chemicals, radiation, etc. For example, a trinucleotide repeat is made up of 3-base-pair sequences, and a tetranucleotide repeat is made up of 4-base-pair sequences. These are grouped into two broad classes based open whether they alter the structure or number of chromosomes. However, radiation-induced mutations are no different from spontaneous mutations, such as polydactyly, color blindness, and Down syndrome. All Time. 1. Inversion: I”, is an intrachromosomal aberration characterised by inversion or reversal of a chromosome segment and the gene sequence contained therein relative to the standard chromosome or linkage group in question. Chromosomal mutations are the change in chromosome structure. Rachel Carson, ecologist who warned about use of pesticides causing mutations in song birds. Mutations in somatic (body) cells may be harmless, or may result in disease such as cancer. A. Chromosomal mutations are processes that result in rearranged chromosome parts, abnormal numbers of individual chromosomes, or abnormal numbers of chromosome sets. These alterations arise spontaneously from errors in the normal processes of the cell. Expected … A Point Mutation Resulting in Nonsense. Doubling dose is the dose necessary to double the spontaneous mutation frequency.
