Gene for blue eye????

I know of a litter that is well bred and one puppy has one blue eye!  Well known champions etc in pedigree so not from bad breeding.  Is blue eye a recessive where each parent must carry recessive?  Also, pup has one blue eye and one brown one.  So would that one  automatically throw blue eyes in litter if other dog had no genetic marker for it or ???  I know....lots of questions in one question.  Any ideas anyonw?

Thanks for any feedback as this 'tis a mystery'!

Blue eyes or abnormal coat

Blue eyes or abnormal coat colors are generally inherited from both the sire and dam as recessive traits. ALL dogs carry recessive genes. Sometimes these traits are expressed due to breeding tightly on common ancestors, sometimes just as random odd luck.

Honestly? I really don't get too frothed up over the news of the occasional appearance of a blue eye or dilute color in a litter, irregardless of the lines or dogs involved. It makes them a pet. If they are a healthy pet, then I'd far rather deal with a blue eye etc... than a heart defect or other truly devastating congenital defect which will shorten or end a dogs' life and devastate the breeders or owners.

Just my two cents. :)

I just thought it worthy of discussion...

I have not seen pup yet since it was born and week old and was gorgeous baby....but baby blue eye is gorgeous in 2 legger kids not 4 leggers.  The more I don't know the more I ask questions so thank you Jen for responding.  I have the basic genetic education so should be, according to HS bio, 2 recessives bred together has 1/4th chance of throwing trait as one would have both recessive traits: BB, Bb, Bb, bb...just haven't seen it much in bullies.  I bred Shelties long time ago and that was common and OK in all but sable shelties really b/c of blue merle gene.

It's a good thing to know about

Genetics are endlessly fascinating. :) And of course no one wants the pretty pup in the litter to have a blue eye!

 

 

Could not agree more Jenn!
