以上由《牛津雙解辭典》中找到的~挺權威的~順便發表壹下我自己的見解~
mutant和mutation皆可表示突變體~記得之前上生物課的時候~mutant貌似更加常用~（我在國外就讀~）而mutantion可以使用得更為廣泛~至於variant~給妳個例子吧~
The story has many variants. 這個故事有很多說法~
看到樓主的補充~又去搜咯壹下~找到另外壹例子~
forty variant types of pigeon~ 四十種變種鴿子~
照這個例句看來~樓主說對咯~variant也可以表示變種~
“mutant 也應該變異株的意思
mutation 是突變的總稱”
樓主回答正確~！
