what color are the girls, white or pointed white (nose and ears a different color)
either way your dealing with those girls hiding LOTS of stuff on you
we know for sure a RED is: A_ _ _ C_ _ _ ee
we know for sure that BLACK is: aa B_ C_ D_ E_
and we know for sure BLUE is: aa B_ C_ dd E_
since our big letters are dominant to our little in order to get 2 little letters we can now add that information into our male making your red: Aa _ _ C _ _ _ ee
now on to your does:
IF POINTED: aa _ _ ch_ _ _ E_
IF REW: _ _ _ _ cc _ _ _ _
your general genese are as follows
A agouti (wild type, multiple colors on 1 hair shaft)
a solid (1 color on the hair shaft ie solid black)
B Black (black based colors like black and blue)
b Chocolate (chocolate based colors like chocolate and lilac)
C is your tricky one
C full color (meaning no adaptations to the hair shaft, black, red, chestnut)
c no color (meaing the hair shaft is "whited out" ie red eyes whites and your pointed colors.
this is where it gets a little compliacated
Cchd Chinchilla (just like the chinchilla rabbit or chinchilla the animal)
Cchl Sable (probably easiest to google a picture of a sable rabbit)
ch Himilayan (your pointed bunnies, like the himi, or Siamese cats)
D Full Color (ie Black or Chocolate)
d Dilute (ie blue and lilac)
E Extention (dictates how far up the hair shaft the color travels, E is full extension meaning color goes form base to tip E= rabbit looks 1 color)
e none extension (gives the rabbit a "shaded look" like a tortoise shell, reds are none extension however despite looking 1 color all over youll notice on a red that they are slightly litghter on their sides)
Es (steel)
ej (harlequin/tri)
given that VERY simplified version we now know in order to produce black and blue one of the parents have to be B
we also know that since you got full extension (black) and daddy is none extension momma HAS to be E
and we also know since you got blue, both paretns have to at least be carrying for dilute
so daddy
Aa _ _ C _ _ d ee
and mommas:
IF POINTED: aa _ _ ch_ _ d E_
IF REW: aa _ _ cc _ d E _
in order to find out if your buck is your B youd need to mate him to a chocolate, if hes BB youll get all black/blues, if hes Bb youll get blacks and chocolates, and if hes bb youd get all chocolates.
same with mommas, breeding them to a chocolate buck if you get all blacks/blues you know shes your BB, if some black some chocolate shes Bb, and if all chocolates hes bb...
one of the parents is definatly B
since you got no whites its safe to say daddies not Cc, or Cch, but he could still carry chinchilla or sable youd have to breed to a chinchilla to find out.
same goes doe your Ds, you need at minimum both parents to carry, but in order to find out if they are Dd or dd youll have to breed each to a blue or lilac.
hope that helps
