Chromosomal mutation
-
Deletion
A region of a chromosome is repeated, resulting in an increase in dosage from the genes in that region.
-
Duplication
A region of a chromosome is lost, resulting in the absence of all the genes in that area.

-
Point mutation
Insertion
One or more extra nucleotides are inserted into replicating DNA, often resulting in a frameshift.
-
Deletion
One or more nucleotides is "skipped" during replication or otherwise excised, often resulting in a frameshift.
-
Substitution
One base is incorrectly added during replication and replaces the pair in the corresponding position on the complementary strand
