What genetic complexity allows two coated Xolos to sometimes produce a hairless puppy?
Answer
The coated Xolo can carry the gene for hairlessness.
Although the hairlessness in the Xoloitzcuintli is attributed to a dominant gene, the interaction between the two primary coat types displays genetic nuance. Specifically, the coated variety is not entirely free of the genetic markers for hairlessness. A coated Xolo possesses the ability to carry the specific gene responsible for the hairless trait, even though their phenotype expresses the coat. Consequently, when two such individuals—both appearing coated but both carrying the necessary underlying gene—are bred, there is a possibility, through the combination of these specific alleles, that they will produce offspring exhibiting the hairless characteristic.
