In numerical taxonomy OTUS for analysis of species are :

  • A.Families
  • B.Genera
  • C.Species
  • D.Populations

Answer: D

For an analysis of species the OTUs are Populations.

In numerical taxonomy the operational taxonomic units (OTUs) are the basic units whose characters are scored and compared. They are always the level just below the groups being studied, so that the analysis can show how they cluster into those groups.

To delimit or analyse species, the units compared must lie below the species level, which in practice are populations (or individual specimens). Families and genera are ranks above the species, and species are the OTUs only when genera are being analysed.
