Types of Aneuploidy

Nullisomy is the loss of both members of a homologous pair of chromosomes. It is represented as 2n-2.

Monosomy is the loss of a single chromosome, represented as 2n-1. 

Trisomy is the gain of a single chromosome, represented as 2n+1. 

Tetrasomy is the gain of two homologous chromosomes, represented as 2n+2.
