Genetically, the Mexican hairless dog without hair are characterized by the lack of hair and some teeth, a phenotype is called canine Ectodermal Dysplasia, and it is inherited as an autosomal semidominante monogénico character.

This means that the feature of lack of hair is determined by an only a non-sex chromosome gene, This gene has partial dominance.

Is due to the partial dominance as the Mexican hairless dog, they have a bit of hair on the head and tail. The Mexican hairless dog without hair are always heterozygotes (HH) -namely, his genotype is composed by a dominant gene (have no hair) and a recessive gene (have hair)- have two recessive genes it turns deadly. The dominant homocigotos (HH) they do not gestate, probably because the affected gene (called FOXI3) It is important in the formation of the ectoderm.

The cross between two Mexican hairless dog with hair (HH) You can only produce a Mexican hairless dog with hair, as a character produced by the expression of a recessive gene. According to the laws of Mendel's genetics, the cross between a Mexican hairless dog with hair and a Mexican hairless dog without hair has a 50% probability of producing Mexican hairless dog without hair and 50% probability of producing Mexican hairless dog with hair (HH, HH, HH, HH), and the cross between two Mexican hairless dog without hair has a 50% probability of producing Mexican hairless dog without hair and 25% probability of producing Mexican hairless dog with hair (HH, HH, HH, HH) the other 25% probability being the dominant homocigotos, that he die before birth.
