Prompt about catching one on dope, aiming for a better race? (7)
I believe the answer is:
eugenic
'better race?' is the definition.
Although both the answer and definition are adjectives, I don't understand how they can define each other.
'prompt about catching one on dope aiming' is the wordplay.
I cannot really see how this works, but
'about' could be 'c' (circa) and 'c' is present in the answer.
'one' could be 'i' (Roman numeral) and 'i' is present in the answer.
'dope' could be 'gen' (both can mean information) and 'gen' is found within the answer.
This explanation may well be incorrect...
'for a' is the link.
Can you help me to learn more?
(Other definitions for eugenic that I've seen before include "To do with science of controlled animal breeding" , "Concerned with racial improvement" , "Designed to improve a race by selective breeding" , "For improving stock" , "Improving by controlled breeding" .)
