Answer:
The correct answer is: extra chromosomes, missing chromosomes, and/or damaged chromosomes.
Explanation:
<u>Chromosome abnormalities</u> are a group of genetic disorders characterized by abnormalities in their chromosomes, whether <u>structural or numerical</u>. This type of condition can be detected by a karyotype.
<u>A karyotype is a laboratory technique</u> used to observe all the chromosomes of an individual to see if there are any problems in it. A karyotype is a picture of all your chromosomes.
A normal karyotype shows 23 pairs of chromosomes (46 in total).
When there's an extra chromosome, it receives the name of <u>trisomy</u> (+ the number of the chromosomal "pair" where there's the extra chromosome). For example: Trisomy 21 - Down Syndrome.
When there's a chromosome missing, that is called <u>monosomy</u> (+ the number of the pair where there's a chromosome missing).
Damaged chromosomes can lead to loss of genetic material or <u>translocation</u> of said information.
