See that's where I'm confused too. I would figure two cream would be CRCR, one CRcr and none crcr. But I'm following what it says on the powerpoint I've been provided.
"-Codominant allele Ccr dilutes red pigment to yellow.
-Fully pigmented red horse is CC at this locus.
-Heterozygous CCcr dilutes bay to buckskin and chestnut to palomino but does not dilute black.
-Homozygous CcrCcr dilutes ALL colors except white or gray to pale cream (cremello) often with pink skin and blue eyes."
Wonder if I can get away with just label it CRCR etc.
The first horse I posted is just a plain ol' chestnut tobiano. Though I think she has frame due to her jagged markings (which I'm putting on the assignment LOL)
It's like they add more letters than they need to for identifying cream x.x
