Very good idea. I don't know the terms either. What is COI? I have a white face blonde pair I am allowing to breed so I can achieve Cool Whip glider status.(see You Tube video) I get completely lost in the genetics. I would love to know where this stuff is written down.
If by "Cool Whip" glider status you are talking about having a large colony, you do NOT want to keep your joeys in with your mom and dad without all males being neutered as Dads will breed with daughters and moms will breed with sons. Inbreeding will indeed cause health issues, fatalities and deformities.
One should NOT be breeding until you are familiar with the kinship chart before you are even aware of what the COI's are of your pairing. As the COI's can actually be relatively low and the gliders can still be too closely related to breed.
Are you ready to find a half eaten joey at the bottom of your cage or inside the pouch? Its not a pretty sight, but one that breeders have to be aware of the chance of finding.
Another good place to learn about breeding is
here. Glider Nursery has a very detailed and informative area for breeding. She also has a facebook page for people to learn at that are interested. Its called Glider Breeding 101.
Folks honestly need to know EVERYTHING about breeding before doing so. It is nothing at all like breeding dogs/cats or even your hamsters.
