'Gene' is a unit of heredity in DNA; 'jean' is a denim fabric or, in plural, denim trousers.
Noun. A unit of heredity encoded in DNA, transmitted from parent to offspring.
Scientists identified the gene responsible for the inherited condition.
She carries the gene for red hair but has brown hair herself.
Gene therapy holds promise for treating previously incurable diseases.
Noun. A strong cotton fabric (denim). In plural: trousers made from denim.
She wore a pair of dark jeans with a white blazer to the meeting.
Jeans were originally designed for miners who needed durable clothing.
The jean jacket she found in the vintage shop was from the 1980s.
Common mistake
"She has the jeans for mathematics" when meaning inherited ability (correct: genes). Or "The gene jacket" when meaning denim (correct: jean jacket). These are rarely confused outside of genetics discussions.
Trick to remember it
'Gene' contains GEN like 'genetics', 'generation', 'genus' — all about biological origin and inheritance. 'Jean' is just the fabric name — denim, from 'Genoa' (Gênes in French), where the cloth was originally made.
Quick rule
Is it the hereditary unit in DNA? 'Gene'. Is it the denim fabric or trousers? 'Jean'.
Did you know?
Jeans take their name from 'Genoa' (Gênes in French) — the Italian port that distributed the heavy cotton fabric to sailors and workers. In 1873, Levi Strauss and Jacob Davis patented copper rivets on denim trousers to prevent pockets from tearing under the weight of miners' tools. Those rivets are why modern jeans still have metal studs at pocket corners. 'Gene' comes from Greek 'genos' (birth, race, kind) — the same root as 'genesis', 'genius', and 'gender'.
Exercise 1 · Pick the right one
The research team identified a _____ that significantly increases the risk of the condition.

Exercise 3 · Form the word
