- degenerate site
- A nucleotide site in a codon that can be occupied by more than one nucleotide and still code for the same amino acid.
-
- degree of divergence
- The extent to which two homologous sequences differ from each other.
-
- deleterious mutation
- A mutation that lowers the fitness of its carriers.
-
- deletion
- The removal of one or more bases from a DNA sequence.

- diagnostic position (see informative site)
-
- diploid
- A chromosomal complement that contains two copies of each chromosome.

- donor site
- The 5' end of an intron.
-
- dot matrix
- A method of sequence alignment in which two sequences are written as column and row headings of a matrix and dots are put in those matrix elements that have identical column and row headings.
