How do you get albino animals?

I'm just curious. Does anyone know why some animals from certain species turn out to be completely albino in colour? Like, there are albino penguins, tigers, lions, ferrets...


I heard that its something to do with inter-breeding, but is that truw?

How do you get albino animals?
The cause of albinism is a mutation in one of several genes. Each of these genes provides the chemically coded instructions for producing one of several proteins involved in the production of melanin. Melanin is produced by cells called melanocytes, which are found in your skin and eyes. A mutation may result in no melanin production at all or a significant decline in the amount of melanin.





In most types of albinism, a person ("or animal" *see note) must inherit two copies of a mutated gene — one from each parent — in order to have albinism. If a person or animal has only one copy, then he or she won't have the disorder.





I added the "or animal" as this applies to people and animals.
Reply:There are various causes all involving a severe shortage of melanin pigment. I've no idea whether inbreeding could make it more likely, but I wouldn't be that surprised if it did.





Checking Wikipedia, apparently interbreeding plays no role in the large majority of cases. That's a myth. (It doesn't state it can't be a factor in any cases.)
Reply:I suppose if you bred 2 albinos, they would produce more albinos, but I think it's a genetic anomaly in most cases. in other words, it just happens.
