Question

A normal chromosome has the gene sequence A B C D E F G ⋅ H I. Which of the following represents a pericentric inversion?

A) A B C D E F G ⋅ H I
B) A B C D E F ⋅ G H I
C) A B C D ⋅ G F E H I
D) A B ⋅ F E D C G H I

Answer 1

A pericentric inversion includes the centromere and changes the relative lengths of the chromosome arms.

Step-by-step explanation:

A pericentric inversion is a type of chromosome inversion that includes the centromere.

In this case, the normal chromosome gene sequence A B C D E F G ⋅ H I would change to A B C D ⋅ G F E H I.

The inverted region includes the centromere and changes the relative lengths of the chromosome arms.
