Possible Het Calculations

Use the possible het calculations chart and calculator to understand recessive sugar glider color genetics, actual het percentages, and traditional rounded advertising percentages.

Chart

Possible Het Calculation Chart

This chart shows possible-het outcomes for recessive sugar glider color genetics. The black percentage is the actual het percentage. The percentage in parentheses is the percentage commonly used for advertising or convenience.

Pairing Het / Possible Het to Normal or Non-Het

The older page also stated that if you are pairing a recessive color to a normal or non-het line, divide the possible-het percentage by two.

Pairing to Normal / Non-HetExpected Possible-Het Percentage

Important Note

A glider is either truly a het or it is not. Possible-het percentages are probability references based on parentage and pairing outcomes.

Calculator

Possible Het Calculator

This calculator estimates the chance that a joey will inherit at least one copy of a recessive gene and the chance that a joey will inherit two copies and visually express the recessive color.

The “actual calculation” and the rounded advertising percentage may be different. The rounded percentage reflects the traditional advertising shorthand used with possible hets.
