Information on European bit inherited (4)
I believe the answer is:
gene
'bit inherited' is the definition.
I can't tell whether this definition defines the answer.
'information on european' is the wordplay.
'information' becomes 'gen' (gen can informally mean information).
'on' means one lot of letters go next to another (in a down clue, letters appear on others).
'european' becomes 'E' (abbreviation e.g. EU).
'gen'+'e'='GENE'
Can you help me to learn more?
(Other definitions for gene that I've seen before include "Hereditary molecule" , "may be passed to child" , "- - Kelly, dancer" , "Part of DNA" , "Biological factor determining heredity" .)
