Q. Monosomic trisomy are represented as
A) $2n - 1 + 1$
B) $2n - 1 - 1$
C) $2n - 1$
D) $2n + 1 + 1$
Explanation
In monosomic condition, one chromosome is missing from the somatic chromosome complement. It is denoted by 2n-1. When somatic cells of an organism contain three copies of one chromosome, the condition is known as trisomy. It is denoted by 2n+1. Therefore, monosomic trisomy is represented as 2n-1+1.
