What does leu het really means?

So if I have a WFB that is 50% leu het, and then I pair him with a normal female or another 50%leu het.

What will the offspring be?

And How Do You REALLY Know If It's A Leu Het or NOT?

Thanks, I'm a little confused

One of the color breeding aficionados will be along to help you soon, I hope... In the meantime, check out Pet Sugar Gliders' article on Color Breeding thumb

Het means they carry a specific gene without expressing it. The percent means the chance they are a Het (they are carrying that gene).

So there is about a 50% chance that your WFB is carrying the gene for leucism. If he is carrying the gene, when paired with a leucistic glider or another glider that is also carrying the gene, he will be able to produce leucistic joeys. But there is an equal chance that he is not.

I will leave the percentages of offspring up to someone else, but with the pairings, you would get all normals or WF/WFB with the pairing of WFB 50% leu het and normal (the would have some percentage of het, but I don't know what that would be). With the pairing of your boy and another 50% leu het you may get normals, WF/WFBs and *possibly* leus (which would prove out both of the 50% leu hets to be 100% leu hets). Again the non leus would be some % of leu het, but I don't know what that would be, I will let someone with more experience explain it.

The only way you can be SURE that you have a leu het is by having leu offspring. thumb

If you pair a 50% leu het with a normal the babies will be 25% leu hets. Which means they have a 25% possibility of carrying the leu gene.

If you paired your 50% leu het with a 100% leu het or a leu and they had a leu baby then you would have proved out your 50% leu het to a 100% leu het. Because they produced a leu you now know they carry the leu gene. If they never had a leu baby then the 50% het does not carry the gene.

If pairing two 50% leu hets together you might not be able to prove one or the other out ever. If one doesn't carry the gene you will never get a leu baby. The only way is if they happen to both carry the leu gene. If they did then they would be considered 100% hets now.

Hop that sort of made sence.

The last don't really make sense to me.

so if I have a pair of 50% leu het and somehow they have a white baby, does that mean I've proved them (the male and female) to be 100%?

or they just have normal babies would that mean the babies are 50% leu het or none?

50% + 50% = 33% possible het joeys
If the 50%'s have a leucistic joey, they'd then be proven 100% hets, and any non-leu joeys would be 66% hets

50% + gray = 25% possible het joeys

Yes, if they throw a white baby, you would have proven them both

or they just have normal babies would that mean the babies are 50% leu het or none?
That would mean that either one or the other does not carry the gene or that both do not carry the gene.

That is right. If they had a leu baby you would have proved them both out. Both gliders must carry the gene to have a leu baby.


If they never had a leu baby, I think the babies would still be considered 25% possible leu hets, maybe even a little more of a percentage, like 33%. Not exactly sure on that one.

When 2 Possible 50% Leucistics produce a BEW then the parents are both Proven 100% Leu Hets.

Th offspring from two 100% Leu Hets paired together will be either a BEW (1 BEW out of every four offspring) and Possible 66% Het for Leu (three out of four babies will be carriers of the Leucistic Gene).

In that situation, the babies would be considered 25% hets. Although both 50% hets would have to be hets to produce white, NOT producing white does not disprove both parents. One parent may still be carrying and possibly passing down the gene.

What if I mix a 50% leu het with a cinnie?

Possible 50% Leu with a cinnamon... offspring would be considered Possible 25% Leu Hets.

My suggestion to anyone who is wanting to prove out a pair of Hets is to breed a lower percentage Het to a 100%. This is so one at least knows which one is a carrier of the gene you are breeding for.
