Perhaps you should try some spelling variations:
"genotypic taxon" » "genotipico taxon", "genotyping taxon", "phenotypic taxon", "genotypic talon", "genotypic saxon", "genotypic faxon", "genotypic tsaxon", "genotypic tfaxon", "genotypic taon"
"genotypic axon" » "genotipico axon", "genotyping axon", "phenotypic axon", "genotypic saxon", "genotypic faxon", "genotypic aon"
"monotypic saxo" » "monotypic sao", "monotypic sexo", "monotypic saco"
"monotypic sano" » "monotypic santo", "monotypic san", "monotypic ano"

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: "((((\"genotypic taxon\") OR (\"genotypic axon\"))) OR (((\"monotypic saxo\") OR (\"monotypic sano\"))))~".
• Removing quotes may allow a broader search: (((( genotypic taxon ) OR ( genotypic axon ))) OR ((( monotypic saxo ) OR ( monotypic sano ))))~.
• Adding a wildcard symbol may retrieve word variants: (((("genotypic taxon") OR ("genotypic axon"))) OR ((("monotypic saxo") OR ("monotypic sano"))))*.
