Variation in Chromosome Structure and their Meiotic Consequences
Embedded Files
Variation in chromosome structure refers to changes in the arrangement of genetic material within chromosomes. These changes include deletion, where a segment of the chromosome is missing; duplication, where a segment is repeated; inversion, where a segment is reversed end to end; and translocation, where a segment of one chromosome is moved to another chromosome. Such structural variations can impact gene expression and are often associated with genetic disorders or developmental abnormalities.
A chromosome mutation where a segment breaks off, flips, and reinserts, reversing its genetic sequence.
A chromosome mutation where a segment of one chromosome breaks off and attaches to a different chromosome.
A mutation where a segment of a chromosome is copied, resulting in extra genetic material.
