Satin vs 'Shiny' Rat
One of the most common cases of mis-identification
we have seen in the registry is satin. Many rats have
been registered as satin, which according to the pedigrees attached, is
very unlikely that it is a true genetic satin. Often, owners/breeders may identify
their rats by phenotype (what they look like) vs genotype (what they
are genetically). This is VERY common when it comes to satin as some that view the
rat think "Oh it's shiny, so it must be satin." Satin is a
genetic mutation just like any other mutation: color, color point, dumbo, etc.
Satin is a double recessive gene where both parents must either carry
the gene or express it in order to pass it on. The registry strives
to record accurate information and therefore feels it important that
traits are recorded based on genotype as well as phenotype. Review
pedigrees thoroughly and register your rats accordingly. If something
doesn't seem to make sense, there is a likely a reason for it.
History of Satin
The original Satins showed up in California at Karen Robbins (KK) rattery in February 1990. They were out of a Cinnamon Pearl and a Pearl Rex (sister/brother pairing) that were from her pure English line. A thorough article of satin origins can be found here.Standards for Satin
