There may be too many or too few chromosomes compared to the normal number.
Parts of the chromosome may be fused to another chromosome in a phenomenon called translocation.
Chromosomes may be turned around in the same chromosome and this is called inversion.
Each chromosome has a specific number.
The long arm of a chromosome is ref2242ed to as “q” arm.
The short arm of a chromosome is ref2242ed to as a “p” arm.
”+” or “-” markers signify a chromosome or part of a chromosome has been gained or lost.
”t” indicates the presence of a translocation between two chromosomes.
”inv” indicates that an inversion has occurred.
