is genus or species underlined
Scientific names come in two parts (thus, binomial), the first part the genus (plural, genera), the second part the species (plural, species). The genus names is always capitalized, and the species name is never capitalized (even if it is a proper noun!).The genus and species names are always italicized or underlined.Recent changes in the nomenclatural code also requires family names to be italicized, but this practice is not universally adopted (they should always be capitalized, however). Following the species name, one sometimes finds additional words.he first time that the organism is named in a paper the full genus and species must be written out; after that, the first letter of the genus name, followed by the full species name may be used. Common names should be capitalized, but never italicized.
