If a chromosomal segment is turned around 180°, the chromosomal mutation is termed a(n)
A) translocation.
B) duplication.
C) deletion.
D) inversion.
E) monosomy.
Chromosomal Mutation
A change in the structure or number of chromosomes, leading to genetic variations and potentially affecting an organism's development.
Inversion
Change in chromosome structure in which a segment of a chromosome is turned around 180°; this reversed sequence of genes can lead to altered gene activity and abnormalities.

Final Answer :
D
Explanation :
When a chromosomal segment is turned around 180°, it is undergoing an inversion. This is different from a translocation where a segment of one chromosome is moved to a different chromosome, a duplication where a segment is duplicated, a deletion where a segment is lost, or monosomy where there is only one copy of a chromosome instead of the normal two.
