Question

If an aberration causes a change in the order of genes on a chromosome but does not alter linkage, it is a case of:

a. Inversion
b. Deletion
c. Translocation
d. Duplication

Answer 1

If an aberration causes a change in the order of genes on a chromosome but does not alter linkage, it is a case of an inversion. In an inversion, a segment of a chromosome breaks off, flips, and rejoins the chromosome. This rearrangement of genes can result in genetic imbalances and abnormalities.
