The unikonts include opisthokonts (animals, fungi, and related forms) and Amoebozoa. By contrast other well-known eukaryotic groups are often referred to as bikonts. Bikonts include Archaeplastida (plants and relatives), Excavata, Rhizaria, and Chromalveolata. These groups may have two flagella (although there are many exceptions).
The unikonts have a triple-gene fusion that is lacking in the bikonts. The three genes code for enzymes which make pyrimidine nucleotides. This must have involved a double gene fusion, a rare pair of events, which supports the shared ancestry of Opisthokonta and Amoebozoa.
