Spider X Albino

If you breed a spider to an albino, you get Spiders that are 100% het for albino right?

What happens if you breed a spider to a Het albino, spiders that may be het for albino? Kinda looking for a cheap route to make albino spiders.

Thanks,
Dan


:salute:

all the offspring will be 50% pos het Albino

You get spiders het albino + het albinos

You get spiders and normal looking offsprings all considered 50% het albino

That's what I meant, I'm just lazy. :D

That's cool though, so then you'd take the spider het albino, and pair with another spider het albino and you get half spider albinos right?

(I know inbreeding isn't right to some people, I'm just trying to see what it takes)

You'd only need to take your Spider het albino and breed it to either a het albino or an albino to have a chance at spider albinos, since the spider is a dominant trait.

You have to remember it is possible het albino! That means only some of the offspring will probably be het for albino, but you have no way of knowing until you breed them and I say it normally takes at least two breedings to a known het producing normals and Spiders before you can say more than likely the gene did not pass. It is a long and chancy route. You would be better off breeding back to your known Het albino to than trying to breed the young ones to each other cause one may actually have the gene and the other may not. That means the albino gene would never come out.

I have a double het for VPI Snow (Parent is the origional VPI Snow made by Ralph Davis) that I plan on breeding with a normal Female this year then beed him back to all the Females that are born when they are big enough while I sell off the males as 50% possible het VPI Axanthic, 50% possible het Albino, and 25% possible double het for VPI Snow.

Yeah, I was thinking about that, but is there a better chance if you have two spiders mating? Probably not right? But that'd be cool to have, a Spider albino. :)

spider isnt a dominant trait it is co-dominant as it only reproduces its self in half the clutch. if it were dominant then the entire clutch would be spiders.

if it were me i would breed a male spider to a female albino then one of the male spider het albinos back to the female albino.

it can turn out to be a very long project if you start dealing with anything less than 66% hets.

It's referred to as dominant because there is no known super version, and so it is assumed that SS and Ss are visually identical, whereas co-dominant genes (PP and Pp) are visually distinct.

The dominant or recessive nature of a particular gene has no bearing on the outcome of the clutch (in terms of percentages of genetic carriers), as that is based entirely on which allele is passed from each parent.

Isnt albinoism (spelling?) a co-dominant? Meaning if you have 1 male and 1 female with the co-dominant gene present, then you get all of those being the same... right?

Dominant, is just a chance that if you breed it to a normal, you'll get some that look like mommy, and some that look like daddy.

Correct me if i'm wrong please.

A dominant trait is passed on to all offspring wether it is a dominant from a trait like pastel as opposed to het pastel or granite.

whereas with spiders and also pinstripes there is no "super" and they do not prouduce all spiders or pinstripes so cannot be dominant

albinos are recessive meaning that the trait only shows in the homozygous form ie. the hets look like normals


as i said before adominant trait is passed onto all offspring

hope this helps

No, it's recessive, which means it has to carry both alleles of the albino gene to be visually albino.

And that is wrong. The passing of traits has nothing to do with their respective nature (dominant, co-dominant, or recessive). The passing of the trait is only determined when the sperm meets the egg, and each gives one half of it's genetic material to the offspring.

and with dominant traits the trait is passed on to all offspring.


like this Super pastel to a normal

http://www.newenglandreptile.com/gra...tics/domXn.jpg


all resulting babies are pastels.

spiders do not have a super and do not pass their trait onto all offspring so it cannot be a dominant trait.

where as i know of a granite that when bred to a normal will produce all granites but whern bred to another granite does not produce a super-granite so the granite trait is dominant not codom.


wheres randy remmington when you need him lol

You are wrong. Dominant just means there is no super form in the snake realm. Dominants act just like Co-dominants, just no supers.

Comparing a Super Pastel to a Spider even genetics wise is way off.

Pastel is a co-dom gene. When the snake has 2 Pastel alleles it is then a homozygous or super pastel.

Spider and Pinstripes are considered dominant, because there has not been a visual super Pinstripe or Spider produced.

Spider x normal

S n

n Sn nn

n Sn nn


Sn= Spider

nn= Normal

SS= does not exist.

Yes, because the animal is HOMOZYGOUS, not because the trait is co-dominant or dominant.

A homozygous spider would, in fact, pass its traits on to all its offspring, however since there is no visual "super form" of a spider, it's assumed that the heterozygous and homozygous forms are the same, hence it is a dominant trait.

Only if the granite is homozygous will it pass on that trait to all offspring. Dominance of the gene is meaningless.

You should probably read through that again yourself. In the explanation, their use of the word dominant is not in the context of the dominance of the gene, but rather in the context of a dominant (heterozygous), co-dominant (homozygous) and normal (non-carrier) animals.

Sooo. An Albino Spider would be sweet.

Make that dominant (homozygous) and co-dominant (heterozygous).

Hey Skoalbasher. You ought to name your Spider Julius Winfield.

I second what the others have said, a Dominant trait is just one that show up the same whether it's homozygous or heterozygous.
PP=NP (identical phenotype)
codominant means that heterozygous is distinct from homozygous PP!=NP (different phenotypes)
and recessive means that it only shows up at all if homozygous
pp only

It IS true that animals that are *homozygous* for a dominant trait will pass it on to ALL their offspring. But as I understand it, there is no homozygous spider (I've heard they think they die off, or maybe there's just no difference in phenotype so it goes unnoticed)

yeah i see where i have misunderstood it now.......you are correct, my mistake was looking at dominance in the context of a codom het and a dominant homo. my apologies for arguing.
