Is there really a difference between PEW and Albino?
That's what I wonder. People argue that white (and black for some reason?) isn't a color. And being not a color means pigment-less (I don't know why people say black isn't a color if anything it has too much pigment I'd think) and albino is lack of pigment.. so..Wait, so, an albino is the absence of all color (the rat could otherwise be black or whatever), while a PEW is the color white?
It's makes complete sense ^^Albinism is pretty complicated. I could be wrong so feel free to correct me. Albinism is a genetic defect that causes a lack of pigment in the skin/eyes/hair. There are varying degrees of albinism so a person with the condition could have red, violet, hazel or blue eyes (most of them do have blue eyes) depending on how much pigment is missing. On the other hand someone with normal genetics could be born with blue eyes also, it doesn't mean that they are albino. I think a good example would be that of a black person with albinism. They are supposed to be dark skinned and have dark eyes because naturally they produce more pigment (melanin) than someone who is caucasian but if they are born with albinism than the genes that control the production of melanin don't produce as much as they're supposed to, so you end up with a black person who is light skinned, blonde, and who has blue eyes. A person who is, for example, from Sweden and is born with light skin, blonde hair and blue eyes would not be considered albino because naturally they produce less pigment, there is nothing defective about their genetics. So a PEW rat is like the person from Sweden and the albino rat is like the albino person. I hope that makes sense, it's so hard to type long responses when i'm on my phone.
I think if there was incest though and both parents/siblings have the recessive gene then i'd happen more.. right?Incest does not cause Albinoism...both parents have to carry the gene for most types of Albinism the only expection is X-Linked Ocular Albinism because it only carried by the mother. So like Blackthorn said its a result of the parents genes. Its like Tay-Sachs both parents must carry the recessive gene to pass the disease to the child.
