Answer:
Chromosome abnormalities can be numerical or structural. A numerical abnormality mean an individual is either missing one of the chromosomes from a pair or has more than two chromosomes instead of a pair. A structural abnormality means the chromosome's structure has been altered in one of several ways.
Explanation:
The most common type of chromosomal abnormality is known as aneuploidy, an abnormal chromosome number due to an extra or missing chromosome. Most people with aneuploidy have trisomy (three copies of a chromosome) instead of monosomy (single copy of a chromosome).
