Perhaps you should try some spelling variations:
"monotypic faon" » "genotypic faon", "monotypic faxon", "monotypic fao", "monotypic aon"
"monotypic fanon" » "genotypic fanon", "monotypic canon", "monotypic manon"
"monotypic danon" » "genotypic danon"
"monotypic axon" » "genotypic axon", "monotypic saxon", "monotypic faxon", "monotypic taxon"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"monotypic faon\") OR (\"monotypic fanon\"))) OR (\"monotypic danon\"))) OR (\"monotypic axon\"))~".
• Removing quotes may allow a broader search: (((((( monotypic faon ) OR ( monotypic fanon ))) OR ( monotypic danon ))) OR ( monotypic axon ))~.
• Adding a wildcard symbol may retrieve word variants: (((((("monotypic faon") OR ("monotypic fanon"))) OR ("monotypic danon"))) OR ("monotypic axon"))*.
