Question

Monosomic and trisomic conditions are

• A. $2n-1,2n+1$
• B. $2n-1,2n-2$
• C. $2n+1,2n+8$
• D. $n,n+1$

Answer 1

Answer: (A)

$2n-1,2n+1$

• Monosomy is a form of aneuploidy with the presence of only one chromosome from a pair. It is represented by 2n-1.
• A trisomy is a chromosomal disorder characterized by an additional chromosome. It is represented by 2n+1.

So, the correct answer is '2n−1,2n+1'.
