Xenowyrm breeding question

[Aries]

Hi. I was not into this breed for long, trying to fill my missing drags. Anyway I noticed something: Two Aso xenowyrm produced Astrapi.

I was wondering is there a rule to breed Xenos, or it's just on chance?

Here you go:

 

Breeding patterns have been confirmed by Birdzgoboom, being based on biomes, and are as follows:

Situation 1: Xeno x Non-Xeno (regular biome):
Outcome 1: the Xeno breeds its same variation
Outcome 2: you get an egg from the Non-Xeno breed
Outcome 3: you get the Xeno corresponding to the Non-Xeno's biome

Situation 2: Xeno x Non-Xeno (Cave):
Outcome 1: the Xeno breeds its same variation
Outcome 2: you get an egg from the Non-Xeno breed
Outcome 3: you get a random egg from the other 5 Xeno variations

Situation 3: Xeno x Xeno:
Outcome 1: They have a chance to breed the Xeno variation from parent A
Outcome 2: They have a chance to breed the Xeno variation from parent B
Outcome 3: They have a smaller chance to breed one of the other 4 (or 5 if both parents are the same variation) Xeno variations.
