Kinship and COI Chart
The chart below can help you set up your pairings. Please note that the older chart is no longer valid due to conflicting information on relationship and COI recommendations when breeding sugar gliders.

Inbreeding - These pairings are very closely related and should be avoided. They have the highest likelihood of genetic defects and issues.
Close Line Breeding - These pairing should only be done limitedly when necessary to achieve, perfect and maintain certain characteristics by responsible and experienced breeders.
Line Breeding - Pairings can be done limitedly to achieve, perfect, and maintain certain characteristics by responsible and experienced breeders.
Distant Line Breeding- At this point some breeders will classify them as "unrelated" and safely paired together with limited possibilities of potential genetic problems.
"Unrelated" - Even though they are technically "related", there are enough genetic differences to avoid most all problems related to inbreeding or line breeding.
COI is more important than relationship. When choosing a pairing, let the COI of the joey overrule the relationship.
The chart above assumes that the COI of the common ancestor is zero. The range of COIs in the relationship chart is a result of full siblings or half siblings from the common ancestor(s).
