kang min » kan min, tang min, kang minah
min dang » yimin dang, mein dank, bin dann
a gene » a genre, a gender, a gentle
wang » wing, wan, lang
yana » ayana, ana, yang
hai » hadi, haji, hari

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: wang yanling yana ((a gene) OR (((human gene) OR (human gender)))) kang min dang hai ;~.
• Adding a wildcard symbol may retrieve word variants: wang yanling yana ((a gene) or (((human gene) or (human gender)))) kang min dang hai ;*.
