In biology, genes are tiny instructions you get from your mother and your father. Some instructions show even if you get them from only one parent; those are called dominant.
In biology在生物學裡, genes基因是are你從爸媽那裡得到的tiny instructions微小的指令you get from your mother and your father（你從媽媽和爸爸那裡得到的）；Some instructions有些指令show即使even if you get them just只從其中一位家長from only one parent那裡得到也會顯現出來; those那些are called就叫做dominant顯性
A recessive gene is the quieter kind: it usually does not show in you unless both parents pass you that same gene. You can carry it and look perfectly fine, and then it appears in a child later.
A recessive gene隱性基因is是the quieter kind比較安靜的那種: it它usually does not show通常不會顯現in you在你身上unless除非both parents pass you爸媽雙方都把that same gene同一個基因傳給你; You你can carry it可以帶著它and look perfectly fine而外表完全正常, and then然後it appears它可能in a child later後來在孩子身上出現
School books love tidy examples (a gene for a trait that ‘hides’), and doctors use the word in the same way. As a noun, a recessive is that kind of gene or trait.
School books學校課本love很喜歡用tidy examples整齊的例子（a gene for a trait比如一個造成某特徵的基因that 'hides'會「隱藏」）, and doctors醫生use the word也用這個字in the same way用同樣的方式; As a noun當名詞用時, a recessive recessive指的就是is that kind of gene or trait那種基因或特徵
Though actually, real bodies are messier than the tidy two-gene story: many features come from lots of genes working together, and some things sit in between ‘shows’ and ‘hides’. In ordinary life this is specialist talk — you meet it in science class and medical news, not in the street.
Though actually不過其實, real bodies真實的身體are messier than比...更複雜the tidy two-gene story那個整齊的兩基因故事: many features很多特徵come from來自lots of genes working together許多基因一起作用, and some things有些狀況sit in between介於'shows' and 'hides'「顯現」和「隱藏」之間; In ordinary life在日常生活裡this這是是specialist talk專業術語— you你meet it會在in science class and medical news科學課和醫療新聞裡遇到它, not in the street不是在街頭巷尾遇到

recessivenoun/ɹɪˈsɛsɪv/

biologygeneticsmedicineA gene that is recessive.
- Suppose, for example, that we started with a population consisting of pure dominants, heterozygotes, and recessives in the ratio 1 : 4 : 4.
