Hi Guys and thanks for the replies :-)
Scottsmum, yes I have emailed my dog's breeder as well, I am just waiting for a reply :-)
Thank you The Spotted Devil, I thought it must be something like that, a simple recessive trait unfortunately the genetics side of things is definitely NOT my strong suit.
I have checked my boys side, he is clear so XX both his sire and dam are also clear XX and also their parents are clear also, so he is clear by parentage. My friend's bitch is DNA clear XX, her dam is also clear XX BUT her sire is a carrier of EIC so Xx.
This is what confuses me because I figure if we mate these 2 technically all pups would be XX or clear too because mum and dad are clear HOWEVER because mum's sire is a carrier of EIC could this be what they mean? She dna's clear but can pass on the EIC from her sire to her pups?
I'm so confused.
I really appreciate all of the replies guys thanks :-)
