Chromosomal Mutation

Inversion

• When a segment of a chromosome breaks off.

• When a segment of a chromosome breaks off, flips, and reattaches.

• When a segment of a chromosome is copied or doubles.

• When a segment of a chromosome breaks and attaches to a non homologous chromosome.

• When entire chromosomes don't separate evenly during meiosis.

Answer explanation

Inversion occurs when a segment of a chromosome breaks off, flips, and reattaches. This process alters the gene order within that segment, distinguishing it from other chromosomal changes.

Duplication

• When a segment of a chromosome breaks off.

• When a segment of a chromosome breaks off, flips, and reattaches.

• When a segment of a chromosome is copied or doubles.

• When a segment of a chromosome breaks and attaches to a non homologous chromosome.

• When entire chromosomes don't separate evenly during meiosis.

Answer explanation

Duplication refers to the process where a segment of a chromosome is copied or doubles, leading to an increase in genetic material. This is the correct definition, distinguishing it from other chromosomal changes.

Translocation

• When a segment of a chromosome breaks off.

• When a segment of a chromosome breaks off, flips, and reattaches.

• When a segment of a chromosome is copied or doubles.

• When a segment of a chromosome breaks and attaches to a non homologous chromosome.

• When entire chromosomes don't separate evenly during meiosis.

Answer explanation

Translocation occurs when a segment of a chromosome breaks off and attaches to a non homologous chromosome, leading to genetic rearrangements. This distinguishes it from other processes like duplication or inversion.

Deletion

• A

• B

• C

• D

Answer explanation

Choice A is correct because it directly addresses the concept of deletion, which is the focus of the question. The other options do not relate to the topic as clearly as A does.

Translocation

• A

• B

• C

• D

Answer explanation

Translocation refers to the movement of substances within an organism. Option B correctly defines this process, while the other options do not accurately describe translocation.

Duplication

• A

• B

• C

• D

Answer explanation

Choice C is correct because it accurately represents the concept of duplication, which involves repeating or copying something. The other options do not align with this definition.

Inversion

• A

• B

• C

• D

Answer explanation

The correct answer is D because it accurately represents the concept of inversion, which involves reversing the order or position of elements. Choices A, B, and C do not correctly illustrate this concept.
