Crossword Genius

A mother's boy (4)

Ross

I believe the answer is:

adam

'boy' is the definition.

'a mother's' is the wordplay.
'mother' becomes 'dam' (female parent of an animal).
'a'+'dam'='ADAM'

(Other definitions for adam that I've seen before include "Biblical first human" , "Man No. 1" , "One of our common ancestors?" , "Man on the ceiling of the Sistine Chapel" , "Faith, for example" .)

I've seen this clue in The Telegraph.
