Perhaps you should try some spelling variations:
"genotypic taxon" » "genotyping taxon", "phenotypic taxon", "genotype taxon", "genotypic talon", "genotypic saxon", "genotypic faxon", "genotypic tsaxon", "genotypic tfaxon", "genotypic taon"
"genotypic axon" » "genotyping axon", "phenotypic axon", "genotype axon", "genotypic saxon", "genotypic faxon", "genotypic aon"
"genotipico taxon" » "genotipico talon", "genotipico saxon", "genotipico faxon", "genotipicos taxon", "fenotipico taxon", "fenotipicos taxon", "genotipico tsaxon", "genotipico tfaxon", "genotipico taon"
"monotypic saxo" » "monotypic sao", "monotypic sexo", "monotypic sano"

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