Question

Classify the following examples and characteristics depending on what type of change in chromosome structure it describes.

Answer 1

Answer:

1. It depends on the DNA region that has been affected by the chromosome rearrangement  

2.Translocations

3.Translocations

4. Inversions

5. Duplications

6. Deletions

Explanation:

A translocation is a chromosome rearrangement where a chromosome fragment breaks off and the resulting portion attaches to another genome region. An inversion occurs when a single chromosome fragment is reversed end to end, thereby also producing a chromosome rearrangement. Inversions can be classified into pericentric (include the centromere) and paracentric (not include the centromere). Finally, chromosome duplications and chromosome deletions are opposite rearrangements where chromosome portions are copied in tandem and eliminated, respectively.
