help in understanding high yellow

[strigoii]

I need help in understanding the genetics of high-yellow morph.
I know, that it is actually normal gecko, but how can one make difference between the look of tangerine and high yellow like this?

Maybe, high-yellow is recessive gene?
What will I get in offsprings, if I will cross high yellow female and patternless male?

Another question - how can one distinguish adult blizzard from adult patternless (when baby "raindrops" in patternless disappears)? To me, they look the same.. :behead:

high yellow is a selectively bred trait. and that "high yellow" looks to come from tang line with most likely some hypo influence. true high yellows have no tang or hypo influence

 

[strigoii]

I can't understand is it a dominant, or recessive?

High Yellow, a true high yellow, is a selectively bred trait. What happened is that breeders began to hold back their normals that had more yellow coloration and then over several generations of line breeding, out of these groups of geckos with increased yellow they started to produce what they called high yellows. True high yellows are rarely on the market nowadays, or if they are, they are called "normals" when in fact, a normal leopard gecko looks quite different being more of a tannish brown body color with lots of black spotting.

Your gecko is actually a Hypo Tangerine, just not a great example of one. However, back in the mid to late 1990's that geckos would be considered a screamin hypo tangerine. Hypo is a term for reduced black or melanin, and is also a selectively bred trait with the exception of course, of the Ray Hine line Hypos, which used to known as "Hypo Carrot Tails" but the original ones were not tangs, they were a pale yellow color. Over the years breeders crossed these Hine line Hypo Carrot Tails into their selectively bred tangerines, which has resulted in todays "Super Hypo Tangerine Carrot Tails".

Oh to answer your question about high yellow being dominant or recessive... they are neither, they are selectively bred.

Great answers Kelli! I saw a really nice High Yellow for sale recently and I'm pretty sure it's still available... :main_thumbsup:

i bet he has a least a little tang in him

Thank you, Kelli.
And what about my question about adult blizzard and adult patternless?

Yeah you're probably right... Maybe I could breed him to a Tang to prove him out... If he's het I think I would get something like 50% Tangs het High Yellow... :main_laugh: :main_evilgrin:

Thank you, Kelli.

If you don't know their genetic background the only way would be to prove them out by breeding to each respective morph.

Nice leo but i would call it a very nice captive normal coz of the amount of spots it has ?.So is the true way to ID a hi-yellow by a nomal looking leo but is very yellow or do you ID a hi-yellow as being a normal-ish looking leo but has a more reduce spotting ? .

The spotting has nothing to do with it IMO. High Yellow means A LOT of yellow.

I do say a high yellow is a "normal" but these are my 2 and I do think they look quite different.


First is normal female, second is high yellow male.

I guess spotting could be a factor, but if you took it away you'd get hypo. I have a male who looks just like yours geckomandi, but everyone always says he's a normal not a hi yellow, so I don't know. We bred him to a sht and the baby is a strange looking (at least to me) pastelly hypo.

 

[GeckoMandi]

I guess everyone determines it in their own way it seems?? I'm going to breed these 2 later this year and see what pops out.

The first one i would call a reduce normal but still a normal the secand i'd call a normal.

Change my mind i think i'll go down this road instead the term hi yellow i think i won't use.There to meny morphs now to give them the ligfht of day in my view they'll just be pretty normals this is not really the important part but they don't really have any cash value over a normal/normal .In my view a leo that's quite yellow is pretty typical of a captive leo as if you breed a normal to a hypo the babys will tend to be quite yellow so thses day they don't carry much BLING in fact very common.So the pic's below are the way i'm doing things now.

later on when i have the time and once i have woken up i will take a photo og a true normal leopard gecko

Do you mean a typical captive normal or a pure wild line normal ?.

 

[robin]

The first one i would call a reduce normal but still a normal the secand i'd call a normal.Here the way i do thing i like clean cut and dry and i don't do Baldy's.hi-yellow for me is spots on head/cluster of spots in the darker bands on the leo's back/spots on tail.Hypo for me is spots on head/NO spots on body/spots on tail.super hypo for me is NO spots on head/No spots on body/spots on tail.

that first one isnt a high yellow. it has hypo and tang influence init

an old timey captive normal

A 'high-yellow" is a normal looking gecko that has a yellow background. A 'hypo' is a gecko of yellow or tangerine color that has less than 10 body spots. The gecko you posted that you titled "high-yellow" is actually a hypo!
