Breeding alignments function with the same mechanics as a sexual breeding system. Canon does not tie it directly to either sex or gender, both being dynamic within the sun/moon system. Alpha lore has it that it is dependent on the time of day the pet is born.

Trivia: Within lore, there is said to be those born during dawn or dusk which have a dual alignment, but it is not able to be used within site mechanics, though it can be mimicked using the Body Fruit item, which inverts the pet's breeding alignment, making it compatible with the opposite pets.
