Inversion

Explicação

## Step 1<br />The question is asking about a specific type of chromosomal mutation that reverses the direction of parts of a chromosome. Chromosomal mutations are alterations in the structure or number of chromosomes, which can lead to changes in the genetic information carried by the organism.<br /><br />## Step 2<br />The options provided are:<br />1. Deletion: This type of mutation involves the removal of a segment of a chromosome, resulting in the loss of genetic material.<br />2. Duplication: This mutation involves the duplication of a segment of a chromosome, leading to the presence of an extra copy of that segment.<br />3. Inversion: This is the correct answer. An inversion occurs when a segment of a chromosome breaks off, flips around, and reattaches in the opposite orientation. This effectively reverses the direction of the genetic material within that segment.<br />4. Translocation: This type of mutation involves the rearrangement of parts between non-homologous chromosomes.<br /><br />## Step 3<br />Given these definitions, the type of mutation that reverses the direction of parts of a chromosome is an inversion.
