Spider morph question

Hi, I‘m new and I’m still learning about the different morphs and the genetics behind them. I have found out that the spider morph is dominant but I am unsure what that means because if co-dominant genes like pastel shows even in the het form how much more can a gene do when it is dominant?
Just a guess but does it mean that it is homozygous and skips the het even when a spider is bred to a normal for example?

Another thing that I wanted to know is does a bumblebee royal have to be homozygous for pastel or can it be het for pastel and still be a bumblebee or would that be called a spider het pastel?

Welcome to the forum.:welcome:.

I'll give this my best shot. Here goes.

To date: The co-dom and dom Spider looks like a spider (both the het and homo form). Unlike the pastel's homo form (Super Pastel) the spider is still a spider. As far as the BumbleBee's gene (a triple threat breeder) goes. This BP has both Spider and Pastel genes visible, hence the result. Now when this guy is bred to a normal you have the possibility to produce nothing but morphs (triple threat).

When it come to co-doms, doms and recesive genes, the term Het really applies to the recesive type. I know this is confusing but hang in there. You see, with co-doms and doms the results are either there or not. You can either see its a pastel or a normal in a clutch. The term Het for (co-dom / dom) does not apply with this type of genetic trait. With recesive type hets you see all normals in a clutch (albino x normal). At this point all of the scale kids in this clutch are het for albino. The term Het for (resecive) does apply with this type of genetic trait.

A bit confusing but with time and some reading you'll get it eventually. You can do some searches in this forum for some really good reading. Hope this is clear as mud.. Welcome:welcome:

in your terms

het for pastel + het for spider = bumblebee

homo for pastel + het for spider = Killer bee
(this is describing genetics, not what combinations of snakes are needed to make the above morphs, in reality there are many ways to make a bumblebee, and for a killer bee each parent MUST have at least the pastel gene, and either or both can have the spider gene)


Now I said het above because you did, but really you dont call them hets, that is more reserved for recessives in my book.

A pastel, is by definition, het for super pastel... that means the "het" form for the super pastel , is a pastel.

However we just ignore all of that, and because the "het" is a visible morph, we give it a name, and its homozygous aka super form, another name


Pastel, Super Pastel
Cinnamon, Super Cinnamon
Mojave, Blue Eyed Lucy
Phantom, Super Phantom
Yellow belly, Ivory


Super tag can usually just mean "homo" if that makes it more clear.

Why drop the het tags and homo tags? Look at recessives

Het for Albino, Albino
Het for Ghost, Ghost
Het for Axanthic, Axanthic

When the morph is visible, tags normally get dropped... We call an Albino an Albino, but we know it is really homozygous for albinio... Similar to how we call a pastel a pastel, when we really know it is het for super pastel.

Make sense? Im not fully awake yet, good luck!

Great post!

ok... now I'm confused, is there a super form of spider?

Good post snakey.... I was still asleep to use the examples...LOL:P

Super form of a Spider - NO. (or better yet, I have not seen one);)

No. To date, no one has proven a visual "super" form of Spider. Whether het or homo for the spider trait, the snake looks the same. BUT...if you have a homozygous spider (bred to a normal), then all his babies will be spiders...where as, if you have a heterozygous spider (bred to a normal), then about half the babies will be spiders and half will be normals.

That you personally know of. Right? ;)
