Binomial System of TaxonomicClassification Use only the Genus and species- Homo sapien- Felis domestica- Escherichia coli· Genus and species are either underlined oritalicized- Genus is always capitilized- species is never capitilizedSHIHEZI UNIVERSITY

Binomial System of Taxonomic Classification •Use only the Genus and species –Homo sapien –Felis domestica –Escherichia coli •Genus and species are either underlined or italicized –Genus is always capitilized –species is never capitilized SHIHEZI UNIVERSITY
