Question for you 20 years ago when i was racing whippets, myself and a mate bought a pup each, dam was a 32lb race champion sire was a 22lb race champion, what weight do you think the pair turned out to be. Seen some good posts recently re this subject. But get the impression that a lot of guys on here think genetics is a question of basic maths and not a science, judging by all the fractions quoted.
