deletion

In genetics, the removal of a segment of DNA with joining up of the cut ends. as in the loss of a segment of a chromosome. Deletion of a single BASE PAIR is one of the kinds of point mutation. Deletion of a base pair triplet (codon) will result in a protein with a missing amino acid.

Deletion

The absence of genetic material that is normally found in a chromosome. Often, the genetic material is missing due to an error in replication of an egg or sperm cell.
