Pointed White and Ruby Eye White




These are Casey's two Satin Angora juniors in the white group.   Yes, both are considered as white, just different kind of white.   The one on the left is ruby eye white, abbreviated as REW, the one on the right is pointed white, abbreviated PW.

In the genetics series, the "C" series is the most complicated.  The series has 5 components: C, c(chd), c(chl), c(h), c.  The order of dominance is show in the sequence: C is the full color, the most dominant; c(chd) is the dark chin, recessive to C but dominant of the other three; c(chl) is the light chin or the sable gene, it's exactly in the middle of dominance.     c(h) is the himi gene that is responsible for the PW while c is the most recessive that make REW.



Genetically, this black PW is:
aaB-c(h)-D-E-

It's possible to have agouti A but such a PW is considered as a disqualification.    


The REW is like a white sheet covers all the other colors, it's genetics are:
----cc----    Other than knowing that the cc gene, the rest are unknown.  One can infer from the parents to fill in the blank but by looking at the rabbit, the best one can do is ----cc----.


This is a black pointed white English Angora doe from Betty's herd long ago.   How long? 30+ years.




This is a blue pointed white French Angora from Charlotte, photo taken in the 2013 ARBA convention.    She was the BOB French Angora that year.    Genetically, it's aaB-c(ch)ddE-.   The difference between the blue point and the black point is in the D series.  The black is the "dense" color thus "D-" while blue is a "dilute" thus "dd".


Pointed white is accepted in English Angora, French Angora and Satin Angora but not in Giant Angora.  The only color that is accepted in the Giant Angora standard is REW.
