Answer:
Chromosomal mutation is the change in the structure or number of chromosome.
Step-by-step explanation:
Chromosomal mutation simply refers to a change in the structure of chromosomes.
The structure of chromosome changes as a result of deletion, duplication, inversion or translocation.
Deletion refers to the loss of certain segments of the chromosome.
Duplication of segments of the chromosome leads to repetition of some genes.
Inversion is the change in the order of genes on a chromosome.
Translocation involves the insertion of chromosomal segments into a non-homologous chromosome.
Chromosome number can change as a result of non-disjunction during meiosis. This may result in aneuploidic or polyploidic chromosomal conditions
