Hi, I have a chocolate Merle border collie and I’m trying to understand her genetics. Her mum was a blue Merle and dad was a brown tri. From what I understand breeding Merle with Merle is bad because of the heath risks, but what colours are considered Merle and what colours aren’t Merle? Is it just the patterns or is any colour other than black and white considered a Merle? There was one deaf puppy in her litter and could the colours of both parents be the reason why? Im not planning on breeding my collie, Im just interested in learning more and to know how to tell a responsible breeder from an un responsible one. Is lilac or wheaten or even black tri considered Merle or they can safely breed with a Merle? Or you can only safely breed a Merle with a black and white collie? again I’m not planning on breeding I just am interested in understanding border collie colours. Thanks so much for your help!
I've been reading a bit about scientists discovering that some dogs have a specific gene responsible for higer learning and verbal discrimination? I'm wondering if any BC breeders had ever considered screening breeding stock for this gene? The gene is called CTNND2 and can be tested for it's presence with a blood sample. Not sure how expensive this would be as that could make it impractical for most breeders. I also know that performance and working ability should be the test the carries the most weight for breeding stock, BUT just wondered if anyone had ever considered that or knew more about it?
According to Anadune database I can expect to get 1-2 smooth coated puppies by breeding my rough coated bitch to a rough coated stud dog. (They both have smooth coated mothers) But I have been told that it is impossible to have a smooth coat from that cross - basically that one HAS to be smooth....just curious which is correct.... Thanks!
