If this is the bhp in the gallery, it's what's called "amelanistic" i think. basically its a different level of lacking black pigment.
a true albino animal has no dark pigment whatsoever, hence the white/light body colours, and pink eyes. amelanistic is lacking a lot of pigment, hypomelanistic is lacking less... the animal may have fairly normal patterning just much lighter colours (see the young 'hypomelanistic' coastals that are around a little).
I'm also pretty sure that albinism is nearly always a recessive trait, if anyone has heard differently please correct me.
this means that a heterozygous animal would appear completely normal, but carry the gene for albinism. if mated to another heterozygous animal, the offspring (on paper) would be 25% normal, 50% heterozygous, and 25% albino. mating to an albino would produce 50% albino and 50% het.
i could go on for ages but will stop there hehe, not even sure if that really pertains to this post! but if anyone wants to know anything else, or if i need to clarify, please ask.
Also the only genetically proven trait i know of in coastals is called the "jaguar coastal", first bred in Norway - i know they've been talked about on these forums before! i've never heard of or seen an albino coastal..
