Verified step by step guidance

Understand the concept of chromosomal rearrangement: Chromosomal rearrangements involve changes in the structure of chromosomes, which can affect the number of copies of genes present.

Learn about gene dosage: Gene dosage refers to the number of copies of a particular gene present in a cell or organism. Changes in gene dosage can affect the expression levels of genes.

Identify types of chromosomal rearrangements: Common types include deletions, duplications, inversions, and translocations. Each type can have different effects on gene dosage.

Focus on unbalanced rearrangements: Unbalanced rearrangements result in a change in the number of copies of genes, leading to an increase or decrease in gene dosage.

Recognize the term 'unbalanced': In genetics, an unbalanced chromosomal rearrangement specifically refers to changes that alter gene dosage, affecting the organism's phenotype.
