Is there a site anywhere that shows what colors/patterns are dominant.
So far, the only thing I have found is white or white headed animals are allelic traits that also contains the trait for deafness.
Trying to learn about ferret genetics. However, It seems it is limited or I am looking in the wrong places.
I come from a reptile breeding background so I have an excellent understanding on how traits are passed along.
Thanks in advance
Justin

Hi there are books available on ferret genetics ( I am afraid a lot contradict each other lol ) but the old fashioned basics are
true bred poley x to true bred poley = all polecat ( dominant gene) true bred albino x true bred albino = all albino ( recessive gene ) true bred poley x true bred albino =*poley
a * poley has the look and colour of a polecat but carries both recessive and dominant genes the albino gene is masked by the dominant poley gene these are known as splits
*poley x true bred poley=75% poley 25%albino *poley x*poley = 50% albino 50% poley
the in-between colours from these mating's can be sandy silver ect it simply depends what mix is in the parents and grandparents back grounds ( think adding white paint to a can of black the more you add the different shades you can obtain remember not all pole cats are black a lot are dark brown ) hope this helps take care bye for now Bev

The absolute best book, albeit simple is the Fret Popper's The Coat Colour Book...the genetics of coat colourations in the domestic ferret. It is out of print, you will have to do back door book dealings to find it but it does a great overview of the colours and all the dire problems that have been created when humans mess with nature ciao

Crazy lady: I assumed alot of it was simple mendelian genetics. I was cursious if they were primarily dominant recessive or were there codominominant, polygenic, allelic. I assumed t he albinism was simple recessive as it is in most animals. I was more curious about the other phases or patterns I have saw cinnimans choclates, champegnes. black sable or "self" ferrets.
I also raise rats for feeders and sell surplus to my LPS. I've learned alot about rat color genetics through this.
Heather: Thankyou for the info on the book.

There is a break down of the various colours and there is discussion about silvers, dilutes, roaning, neural crest, DEW, Irish spotting etc. and the correlation between these "special" colours and the associated health risks in this book. It may not be as in depth as you would like though you could probably apply your knowledge to the overviews given to draw some reasonable conclusions. ciao

Hi a lot of sandy / cinnamon begin by breeding a split albino to a split brown poley the resulting offspring is then bred to a split sandy once again and so on in some sandy / cinnamon you will see the strong mask of the poley in others the mask is really diluted going back years ago the first silver was bred by a friend of mine from a pure albino father to a split poley mother who was showing signs of roaning ( she was really washed out and light in colour ) she produced a split litter of poley albino and light silver hense the silver craze was born the same applies to dark eyed whites most dark eyed whites contain some dark guard hairs somewhere on there body but as they age the guard hairs get less and less and usually by the age of four or five have taken on the appearance of a pure dark eyed white ( pure white coat and dark eyes ) the black self you talk of is normally due to the mating of a mink and a polecat it has virtually no mask and has no or virtually no undercoat with a tight short coat the skull is small and pointy and the eyes are small and round ( the head takes on the characteristics of a mink ) I cannot comment on the book heather has recommended but I am sure it maybe of some help take care bye for now Bev

Thanks Crazy Lady for the detailed explaination of your experience. Very nice to have some one share what they've seen. No different than humans, different colors mean different genetic make-up and problems can and do arrive. Look at gingers for example...what aout them makes their skin so suseptable to the sun vs a standard brunette. Why does the skin have to be less protective just because the hari is a different color.
We have a dog with a white patch on her head. poor things got sunburnt the first couple of times at the park till we realized it.
So why would anyone think this is different for our little fuzzbutts? Play with nature, take the good with the bad. I personally just wish they'd leave em' all alone and let them be what they were intended to be.

Boy do I second the leave them alone comment ! over the years when judging I have been presented with classes marked as Dalmatian ( poleys crossed several times with albino so the coat is simply splodges of black in different places ) sable angoras ( which are actually dark grey (and half poley half angora ) and colours which tend to suit which ever breeders are selling in that area ( new names get invented for them lol ) it was a lot simpler when over here in England there was four classes poley albino sandy and any other colour ( in this class it could be sky blue pink the only thing that was really important was body shape eyes skull ears teeth and overall health and temperament colour counted for nothing ) they also used to be judged on could any of the ferrets in any class do the job nature intended them to do which was hunt take care bye for now Bev

I would find it interesting to know a bit more about the genetics behind colours in ferrets too. I personally like sables (the darker the better), although do have sandies and albinos as its unavoidable and I love them all regardless of coat colour. I have noticed that split poleys have a lighter colour, where pure poleys are darker. I also wondered how chocolate fits. I have one jill here from pure poley lineage who appeared to be a light sable as a kit and as she has matured she has turned a rich mahogany colour, her son is showing signs he is turning the same too as he started out very light and is turning a very rich colour .... I would also find it hugely interesting to see any unbiased literature on health problems associated with certain colour patterns. Waardenburgs is the obvious one and, despite being striking in appearance, I have always avoided blazed/panda/DEW ferrets for this reason. I also read something somewhere about breeding silver to silver so that is a no go too. Interestingly, the jill I have had most health trouble with is an albino. She had to have an emergency caesarian due to neural tube defects in her litter (although previously had a successful litter) and now has lymphoma. And she is not a split albino.... ...but now I'm rambling

funny I love sables too, but only have 1 out of 7. One is a chocolate and all 5 girls are white.
