Question

before after the mutation above best represents a(n) monosomy inversion nondisjunction deletion

Explanation:

To determine the mutation type, we analyze each option:

• Monosomy: Loss of a chromosome, not shown here.
• Inversion: A segment of a chromosome is reversed. In the diagram, the segment with C, D, E becomes E, D, C (reversed), matching inversion.
• Nondisjunction: Failure of chromosomes to separate during cell division, not depicted.
• Deletion: Loss of genetic material, not seen here.

Answer:

B. inversion
