Orange or Fawn or??

[Cedar Point Rabbitry]

This is Shance & Shannah, brother/sister Holland Lops. They're tris, but I'd like to know what kind of tri I mean, Shance is so much lighter then Shannah! Is he a fawn and is Shannah an orange?

 

[Dood]

Both look agouti and black, the colour intensity difference could be due to Rufus factors or Shannah being wideband

 

[Cedar Point Rabbitry]

What do you mean by agouti and black? And how would I tell if Shannah is wideband & what exactly does that mean?

 

[Dood]

There are over a dozen known colour genes in rabbits called "locus", agouti, black and wideband are three of them - here are the others rabbit-genotypes-list-t19367.html

Oh, okay, I get the wideband part now. I've studied color genetics a fair amount but it seems to go in one ear and out the other :lol: never sticks well!

On Evens Rabbit Register, I get to pick from the following tri colors:

1)Tricolor = shows no genotype for it
2)Tricolor - W/Blk/G-Org = Aa B C D ej W Enen
3)Tricolor - W/Blu/G-Fawn = Aa B C dd ej W En en
4)Tricolor - W/Choc/G-Org = Aa bb C D ej W En en
5)Tricolor - W/lil/G-Fawn = Aabb C dd ej W En en

So, if I'm understanding right, Shannah would be either #2 or #3? What would Shance be?

If it helps at all, their sire is a Japenese Harlequin.
And their dam is the doe we were talking about over here:http://rabbittalk.com/topic24950.html
who you said genetically was:
genetically a broken tort with a harlequin gene (= aa B_ C cchl D_ ej e ) instead of a broken fawn/orange with a harlequin gene (= A_ B_ C cchl D_ ej e)

 

[Dood]

#3 (and #5) is a dilute/blue so she is not that

The Wideband effect is a recessive gene and would be "ww" not "W_" so none of those are wideband harlequin

Both look to be black/orange tri; the brightness (boldness of the orange) can vary greatly. Happens with the other tri variations as well.

Okay, so now I'm successfully confused. Genetically what are they? Do I just put in the Tricolor ( with no genotype ) or Broken Harlequin ( which also has no genotype in the program ) for their colors in Evens?

 

[Dood]

Shance - Aa B_ C_ D_ ej_ W_ ENen +

shannah - Aa B_ C_ D_ ej_ W_ ENen ++++
or Aa B_ C_ D_ ej_ ww ENen ++

Thanks Dood! How would I prove of Shannah is W or ww?

 

[Dood]

Test breeding

If bred to an orange/red that is wide band and you produce normal band then she isnt

 

[Cedar Point Rabbitry]

Okay....and how would I know a rabbit has the wideband locus?

Thanks sooo much, Dood, for answering all my questions!!! :thankyou:

 

[Dood]

Orange or reds with orange or red bellies are wideband, as are tans and chestnuts in several other breeds

Oh, okay! Thanks Dood!
