andalusian blue vs self blue

[muzzles&nuzzles]

Andalusian blues are the blues that are darker on top then lighter on the bottom? More of a two tone blue correct? Well that is what I have and that is what I was told they were.

Self blues are lavender, more of an all over one color? Or is self blue seperate from lavender? Either way, I would think you would breed andalusian blue birds to one another then keep the self blues together? Is that correct?

Not this thread again....LOL I am sure I will not get something correct here, but Andalusian blues bred together will produce black, splashes, and blues. Self blue and lavendar are the same, I think, as they will both breed true if bred to a self blue/lavendar.

Apparently this is a popular question. Maybe it needs a sticky.

Anyways, hobby names and genetic/gene names are not one-and-the-same. Andalusian blue refers to, as the OP stated, a bird with darker plumage on the head, hackles and (on males) saddle. This appearance is caused by the heterozygous state of the blue gene. Genetically the bird is Bl/bl+, carrying one copy of blue and one of not-blue.

Self blue is a term that means different things in different coultries. In the US it is usually considered synonymous with lavender, which is genetically lav/lav. As a recessive gene it breeds true, which is one use of the term self; another use of the term refers to a solid coloured bird--all plumage is identical in colouring--no primary oe secondary patterns.

In Australia and Europe breeders have created a solid coloured (self) blue bird based upon the blue gene.

I think it does need a sticky. There are so many posts they are hard to find.
You would want to keep these genes seperate?

Most people do, but at least in silkies, lavender has been bred into many blue lines for a number of years. When only one copy is present there is no way to know that it is there.
