What are POG's then ? I understand they are called Pastel Orange Ghosts, but how can this be a possible morph? Doesnt the Orange Ghost allele have to be paired with another Orange Ghost allele, in order for the recessive trait to be visible? Am i making sense ?
Both parents had atleast 1 ghost allele
Pastel het Ghost x het Ghost
trust me it possible, I own one :)

Since I was offered a Pastel Het Orange Ghost Female, it got me thinking..
If you mixed a Pastel x Orange Ghost, (P = Pastel allele, p = normal allele, G = OG allele)
So 50% would be GgPp (or Pastel het OG), and 50% would be Gppp (or Normal het OG)

Yes, you are making sense. You are right. An orange ghost has a pair of orange ghost genes. A pastel orange ghost has a pastel gene paired with a normal gene and a pair of orange ghost genes.
In the Punnett square in the quote, p is the normal allele for the pastel mutant gene. The normal allele p is not the normal allele of the orange ghost gene.
P = pastel mutant gene
p = normal allele of the pastel mutant gene.
g = orange ghost mutant gene
G = normal allele of the orange ghost mutant gene.
The convention is that the more dominant gene gets the upper case letter and the more recessive gene gets the lower case letter.
Pastel (Pp GG) x orange ghost (pp gg) -->
Each sex cell (sperm or egg) gets one member of each gene pair. The pastel produces 2 types of sex cells -- P G and p G. The orange ghost produces one type of sex cell -- p g.
1/2 Pp Gg = pastel het orange ghost
1/2 pp Gg = normal looking, het orange ghost
The fractions are the odds of a given result per egg, not per litter.
To make a pastel orange ghost, one would mate a pastel with an orange ghost to make pastel het orange ghosts. Then mate one of them to either and orange ghost or a het orange ghost, We would expect some of those babies to be pastel orange ghosts.
