Punnet square type question, percentages?

[imbrad2003]

Blazing Blizzard 100% DB Het x Tremper Albino 100% DB Het, father was a full Ruby eyed DB for all of my 4 animals, 1.3.

What are my chances at DB full ruby eyed offspring:main_huh:

Whether a DB will have full eyes or snake eyes cannot be determined with a punnet square. It seems to be totally random.
