I know albino horses are near impossible to produce. If they do live to term, it's for no longer than 48 hours because the same gene causes the failure of an organ to fully develop (somewhere in the gastrointestinal tract). Correct me if I'm wrong, but that's what I remember.
What genes cause a 'true white' horse? What is the difference between a true white and albino?
Also, I am somewhat familiar with perlinos and creamellos, but how are they different from true whites? Most that I've seen are a creamy color, but some are definitely white. How do you know the difference between one of those and a true white?
Here are two pictures I have come across on a 'true white' horse that isn't supposed to be white at all. What would make that happen?
