Question

Quizplus · Accepted Answer

Inversion is the type of chromosomal rearrangement where a segment of DNA in a chromosome is reversed in its orientation. This means that the order of genes in the affected region is rearranged, but the genes are not lost or gained. Inversion takes place within the same chromosome, and it can have no effect, some effect, or a significant effect on the phenotype of the organism, depending on factors such as the location and size of the inversion. Duplication and deletion both involve gaining or losing a segment of DNA from a chromosome, while translocation involves the exchange of DNA between two non-homologous chromosomes.
