The relation of body score (body height/body length) and haplotype E on Phu Quoc Ridgeback dogs (Canis familiaris)

Abstract

Phu Quoc Ridgeback dogs (Canis familiaris) were one of the endemic species of Phu Quoc Island – Vietnam, This animal is one of the rarest dog in the world, which has a ridgeback. The haplotype E, one of the breed dogs rare haplotype, high percentage 16.67% in the Phu Quoc dogs observed. By the bootstrap method, we estimated and accurated the morphology characteristics differerence between haplotype E (hapE) and others group (nonE) of Phu Quoc ridgeback dogs. The difference of body score (height/length) between haplotype E dogs group and non-haplotype E dogs groups which calculated by bootstrap method [0.001 - 0.068, 95% CI], it is more accurate than t-test methods [-0.007 - 0.077, 95% CI], The results by regression logistic showed that the haplotype E occurrence probability can be predicted based on body score (body height/body length ratio), when this ratio increase 0.046 standard deviation, the haplotype E occurrence probability increase 47%
