The appearance of a different DNA sequence may decrease nucleotide diversity.
Nucleotide diversity may be decreased when a different DNA sequence type appears in a population. This undesirable property in a genetic diversity index is demonstrated by mathematical examples. The possibility of this phenomenon in natural populations is briefly discussed.
