"i was wondering about the genetics on pastels. also, could anyone explain to me what a co-dominate, dominate, double hets, triple hets, why i see more ghosts as DH hets, and also, the genetics of ghosts. if anyone has any info on my questions, please post,
cheers"
As I understand it, Pastel is a specific line of Hypo.
Hypo is a dominant trait.
Het = heterozygous = having one gene within a gene pair, ie het for albino means having one albine gene and one normal gene. Also applies to dominant traits like hypo, het hypo woulod mean one hypo and one normal gene but since Hypo is dominant, the animal looks hypo.
Homozygous = having both genes within a gene pair the same. Hom for albino would have two albino genes and look albino. Hom for hypo would have two genes for hypo and look hypo.
Dominant = trait where there are not significant 100% distinguishable traits between the het and hom animals
Co-dominant = Trait wher the Het and Hom anaimals are 100% identifiable.
Ghost is Hypo/Anerythristic. Could be het for hypo/hom for anerythristic or hom for both and still look basically the same.
A "double het for ghost" would have one hypo gene and one anery gene and would look like a normal hypo.
