13:18 Russian blue hamsters/Статья про русских голубых хомяков на английском языке |
Full text with illustrations is available here
This story began in November 2010 when I noticed in an ordinary Moscow pet
shop among other Syrians hamsters an animal whose colour I couldn’t identify. It
looked a lot like blue, but it had black staining all over his body making him look
"marble”. His eyes looked totally black, his ears were blue also with the marbling.
At that moment I had no space in my hamstery for a new animal, but the
temptation was so strong that I decided to return to the shop three days later
and , if this enigmatic hamster is still there, to buy him. This I did and was pleased
to find that although the other hamsters had been sold this one remanined.
I called him Tim Taler.
Two months later I noticed, in another pet shop, a female of the same colour. I
told this to my friend, also a hamster breeder who immediately brought the
hamster and called her Molly Moon.
Molly Moon had a surprise for us in that she soon gave birth to a litter of four. Two
white ones (unfortunately they died while still in the nest), a black banded male
and golden female La Souris Mirasol who came to me.
Five months later I paired Tim and Mirasol.
I was excited to see that at least one baby has the same mutation as his father and
grandmother. While the babies were growing, it was obvious that five of them
have marbled coat shown by Tim and Molly. So, we had 12 young;
Four black,
Three golden,
A single animal the same colour as Tim and Molly (her eyes are neither black nor
red, they look cherry-coloured at the first day but just in a few days turn black),
One Lilac looking, but with much darker ticking and also showing the
marbling,and dark ruby eyes not red.
Three cinnamon-looking these had darker ticking, eyes and ears that you would
expect from a "normal” coloured cinnamon. I thought that this had to be the basic
colour of this new colour and have provisionally call it "Russian cinnamon” . This
may need to be renamed at a later date when more information and studies have
been undertaken.
The second Tim’s litter (Point Barrow D) gave us a pleasant surprise, there were
Russian blue and Russian cinnamon babies, though the mother (red-eyed offwhite)
didn’t have this mutation. Obviously, the first thought we had was that the
gene of Russian blue is dominant. But further investigations showed that
everything was more complicated. I won’t itemize here all the litters obtained
within the framework of the project, but we ascertained its coherence with
cinnamon.
In the litters of a Russian blue (Russian cinnamon etc.) and a red-eyed
(cinnamon+) hamster all the babies are either red-eyed or Russian blues.
Pairing RBs to a cinnamon carrier we receive about 25% of RBs and 25% of
cinnamon+ babies, while in pairings to a hamster who has no cinnamon gene
neither cinnamon nor Russian blue appears.
These facts generated a new hypotesis: the marbled gene can be mutation in Plocus,
recessive towards "normal” P but dominant towards cinnamon (p).
Though we don’t write off the possibility that the gene is dominant but can only
be seen on cinnamon-based colours giving a "shadowing” effect (such as, e.g.,
umbrous that changes a lot cream-based and yellow-based colours, can be seen
on some agouti colours but can hardly be determinated on such colours as dove
or blonde).
One of the most important latest news in investigation of this colour was getting a
homozygous Russian blue.
His phenotype doesn’t differ a lot from a heterozygous form, but in pairing with a
cinnamon+ female he gave a litter of RBs and Russian blondes only. Now we are
on the way to find out if the gene is located in P-locus or not, for this we'll have to
pair Disney with a black eyed female and then pair one of his black-eyed offspring
with a cinnamon+ or carrier. If in the litter there are both RB and cinnamons - it's
another locus, if there are only Russian blues and black-eyed babies - then almost
certainly it's P-locus.
There are still lots of questions about this gene and its influence to other colours
to be answered. I hope that more breeders both in Russia and in elsewhere will
join this interesting investigation and together we’ll reveal all its mysteries.
