How Are Albino's Created?

[VidVid]

hey..just out of curiosity, how are albino varieties created??? Lets say their are no albino kribs, then miraculously, their is only one offspring out of hundreds born with this albino trait...they are then paired up with other albino's from a different batch and their albino genes pass onto their offspring...Is this how they are created???

i think its a mutation in the genes bit like blue budgies

Yes, it's a mutation affecting the production of the pigment melanin. That's why all true albinos have pink eyes - melanin is necessary to produce eye colour.

The reason you don't tend to get albinos from non-albino parents isn't just that the gene's recessive, but albinos often don't survive to adulthood when left to grow with parents/siblings because of their usually poor eyesight, dislike of bright lighting and ergo inability to efficiently compete for food.

[codebox] It works like this: Large letters represent each loci,
with smaller superscripted letters representing the alleles for that loci.
Normal or wild-type alleles are represented with a +. An example for an amelanistic specimen: aaaa.
using the previously accepted method of notation, it would simply be: aa. A specimen heterozygous
for amelanism would be represented as: a+ aa.

While this may appear only to be twice the letters and nothing more,
the real value can be seen when used to describe the various Ultra, Ultramel,
and Albinos from the example above: aaaa= Albino; auau= Ultra; aaau=Ultramel.
Notice that we can now see that all involve the same loci (a) but the different alleles can now be seen at that loci (a or u).
Better still, we can now see the various allele combinations present and easily predict what
offspring we will produce from any given pairing! This would be impossible using the older system of notation.[/codebox]

clear as mud to me
