Who is the dominant trait in a mule?

Mules are hybrids resulting from the crossbreeding of a male donkey (jack) and a female horse (mare). They typically inherit traits from both parent species, but they are sterile and cannot reproduce. In terms of dominance, mules often exhibit traits such as strength, endurance, and intelligence, which are considered advantageous for their work purposes. However, they do not have a singular "dominant trait" as it varies depending on the specific traits inherited from their horse and donkey parents.
