Trisomy
Also known as: chromosomal triplication
- 1Defined by the presence of three copies of a specific chromosome.
- 2Classified as a form of polysomy.
- 3Categorized as a type of aneuploidy.
- 4Represents a deviation from the normal diploid state of two chromosomes.
- 5Can lead to significant biological consequences due to excess genetic material.
A trisomy is a type of polysomy in which there are three instances of a particular chromosome, instead of the normal two.

central concept in his genetic research
Epstein's research focused on the biological consequences of trisomy, particularly how extra chromosomal material disrupts normal cellular and developmental processes.
Trisomy is a specific form of polysomy characterized by the presence of three instances of a particular chromosome instead of the standard pair. This condition represents a deviation from the normal chromosomal count in an organism's cells.
Karyotype of a human with Trisomy 21 (Down syndrome)Wikimedia Commons: File:Trisomie_21_Genom-Schema.gif As a type of aneuploidy, trisomy occurs when there is an abnormal number of chromosomes. This chromosomal imbalance can have significant biological consequences, as the extra genetic material often disrupts normal development and cellular function.
