Final answer:
Genomic rearrangements of segmental duplication repetitive DNA can result in a longer chromosome, abnormalities, and genetic disorders. Duplications and deletions can have serious consequences, while inversions and translocations are generally less problematic.
Step-by-step explanation:
Genomic rearrangements of segmental duplication repetitive DNA can result in several outcomes. One possible outcome is the creation of a longer chromosome when a segment of DNA is repeated, leading to multiple copies of genes in the chromosome.
These rearrangements can also cause deletions, duplications, or translocations, which can result in abnormalities and genetic disorders.
Duplications and deletions, especially when they involve a large number of genes, can have serious consequences for individuals, while inversions and translocations are generally less problematic.
