How does a scientific name appear when written?

In addition to mentioned above, once you have written a species name in a paper/essay, you can then abbreviate it (still in italics):


H. sapiens





This comes in handy when writing about multiple different species.





And as for subspecies, still in italics:


Canis lupus familiaris





Which abbreviates to:


C. l. familiaris





If writing it out, instead of typing, then underline it. It's a bit hard to italicise handwriting :P

How does a scientific name appear when written?
It is written as "genus species" but must be italicized, and never capitalized





Ex: homo sapien (But italicized)
Reply:the genus is capitalized... but other than that see above





EX. Homo sapiens
