What physical trait common in the hairless variety is genetically linked to the dominant hairless gene?
Answer
The frequent absence of some premolars.
A significant physical characteristic noted in the hairless variety of the Xoloitzcuintli involves their dentition structure. It is an acceptable and frequently observed trait within the breed standard for these dogs to exhibit a deficiency in their teeth, specifically missing some premolars. This dental irregularity is not arbitrary but is directly connected genetically to the presence of the dominant hairless gene that defines this variety. While owners must ensure the overall bite remains correct, the missing premolars themselves are a known consequence of this specific genetic expression affecting both skin and tooth development.
