There was a highly significant within-family association between red/blue coat colour and deafness (p = 0.00036), with red coat colour segregating more frequently with deafness (COR = 0.48).
There was a highly significant within-family association between red/blue coat colour and deafness (p = 0.00036), with red coat colour segregating more frequently with deafness (COR = 0.48).
Facial masking showed a weakly significant segregation with deafness (COR = −0.28, p = 0.036).
Firstly, taking a direct approach that ignored pedigree structure, there was a modestly significant relationship between red/blue coat colour and deafness (p = 0.045), with red dogs being 1.84 (OR 95% C.I. 0.98 to 3.48) times more likely to be deaf.
The relationship between deafness and coat speckling approached significance (p = 0.07), with the lack of statistical significance possibly due to only four families co-segregating for both deafness and speckling.
