#109725 - 06/12/06 12:45 PM genetics clarification on wf hets
Anonymous
Unregistered


I have been reading some posts on there being no such thing as a wf het. Does this mean for sure that breeding to wf hets together will NEVER produce a wf? Is this considered a dominant gene?
So a leucistic is recessive in that there is a het leu?

Thanks for any clarification anyone can give me!

I wish I could help you out on this one myself but when it comes to genetics I am so confused and lost!!

I personally always thought if you have two WFB and they have regular grey joeys that you would still have a chance at getting wfb babies out of them but the way people make it sound that would not be the case. <img src="/ubbthreads/images/graemlins/nixweiss.gif" alt="" />

As far as I understand, there is no such thing as a "WF Het". One parent must express the color trait inorder to produce a WF. One WF with a Normal can produce a WF. Two WF's can produce a WF. But two "hets" cannot produce a WF.

I believe that the WF gene is a Co-dominate gene. Correct me if I'm wrong.

I have read that there was a WF het to WF Het pairing that produced a WF joey, but all it seems to be is a rumor.

It is just a rumor that some one did produce a wf from two hets. You can put two normal joeys that come from wfb parent/s but you will never get a wfb baby. 2 hets for leucistic (if they carry the gene) will have a leucistic joey

So the gene for wf is a dominent gene where you only need one chromosome with the gene in it to make the baby. In that case to be a grey it would have to have one gene from both parents that was not wf. right?

Becky (bjsides) had a WFB and a Grey that had Sun SUn and hes a gorgeous wfb! But here 2 wfb pair had a grey and a wfb i would say that duke is a wfb het since he had 2 wfb parents?

Gene responsible for White Face Variation is C0-Dominant.

Gray/brown is the dominant wild color of a Sugar Glider.

Dominant and Co-Dominant genes only need "one copy of this gene from 1 parent" to reproduce the color for the variation one is breeding for.

Leucistic Hets... one copy of this gene is needed from "each parent" to reproduce the all white variation. Thus... the gene is Recessive.

The gray offspring produced by two 2nd generation White Face Blondes is "not" a het.

Although these Gray colored babies are beautiful... they will never produce the all white face of the White Face Blonde.

All this just confuses me. I tried to compare it to what I learned in science class and got MORE confused. (How two people with black hair brown eyes and dark skin can have a blonde haired blue eyes fair skinned child, and vise-versa.)
**shakes head** I'll just believe what is said and not try to understand why.

White Face Blonde is not dominant over Gray. Being a Co-Dominant gene there is an equal ratio of producing Gray or White Face Blonde.

White Face Blonde x Gray will produce on average 50% Gray babies and 50% White Face Blonde offspring.

Wtih multi generations of White Face Blondes paired together... the ratio appears to increase with some pairs to 75% or better.

This is based on my experience as a breeder with five breeding pairs of White Face Blondes for four years.

if a grey baby cannot produce a wf with another grey baby both born from a wf which is what you are saying, then the wf gene is dominent. meaning both of their parents would have to have the code Gg where 25% of their babies would be grey.

I am also a firm beleiver that there is no such thing as a wf het. In easy terms, for a glider to be a het, should mean that when paired with a het of the same color, they can produce a glider of color; this is not true in the WFB gene. I do still call my grey joeys out of WF parents hets, I think the reason I still list them as a WF Het is so that they buyer is aware that the glider has a parent of color; but I do plan on changing it.

My question is where did the first wfb come from? Was the parent/s wfb as well and since they didn't know so much about gliders back then they just thought nothing of there color difference?

That is an excellent questions and one I would also love to know the answer to.

Also, why are there so many breeders that advertise wfb het if there is no such thing? <img src="/ubbthreads/images/graemlins/littleglider.gif" alt="" />

I dont think alot of breeders are aware that wfb cant be het. either that or they are trying to get more money for their joeys which i see as a scam becuase ididnt know this was true untill i researched it.

Nothing was thought about the color difference for years.

Rememeber... in the wild... an animal with a noticable color difference is usually plucked off by it's preditor. So, the White Face variation was not seen until the gliders were here in the states. And even then it was not noticed for many years thereafter.

Mike Sandridge has never revealed the source as to where he purchased his first three White Face Blondes which were Cereal and his two female offspring .... Pearl and Pricess. My guess is he got them from a mega breeder and in Texas.

GliderTree... Pele was a rescue and do not know where he came from other than Texas.

Flying Fur Ranch... their wfb stock orig was found in their gray breeders.

Mary Brown... same thing.... wf blondes a few were found in her gray breeders.

Custom Cage Works... they started their line same as the above.

Lisa of SunCoast... well, she is a smaller breeder compared to the mega breeders. Her program got started from Flying Fur Ranch.

The White Face Blonde was highly sought over yesterday, still prized today and will be even tomorrow. Myself, I feel the Co-Dominat gene responsible for this variation is the key to future color variations.
