BTW, on average, if you cross two carriers of a recessive mutation, half of the offspring will also be carriers, and one out of four will express the mutation (blue yorkie, in this case). There are exceptions to the rule (for example a spontaneous mutation occurring in a single sperm or egg cell), but they are rare. |
Oh boy lass, a real live expert. I have a question if we can determine/type color, at least can with the BRT's to try to make sure we don't throwback a brown or golden or grey BRT - are breed is quite young. So I would have thought something similar for the blue born might be able to be done? Or at least we could get closer to a genetic test.
What are your thoughts on this?
