While examining a lot of pedigrees I couldn't help but noticed frequently there are father to daughter breeding in the history, but I have yet to see mother to son(and I'm the first to admit I haven't examined all that many pedigrees) . I was talking to a breeder and they told me that breeding mother to son is a no-no - but not father to daughter. I found that interesting because genetically speaking I don't see the difference between father/daughter and mother/son...any opinions out there regarding any differences between breeding mother to son as opposed to father to daughter (not opinions on inbreeding/line breeding in general, just why it would be ok to breed father to daughter but not mother to son). Just curious.
Thanks to those in the know.
