"What now, biatch?"

Hygene after sex!

Awsome! Good luck with it!

 

[Spider-man 2]

Wow, beautiful male! Would you ever consider making these two communal if you had trouble getting them to breed under supervision?

How do you that is a male of the same species if it is undescribed?

Thanks mate!

Thanks! I don't know exactly what You mean but the mating went well, so I could let them together for a few days.

I have became the "aureopilosum" from different people, but if I'm right, they brother and sister. The male looked before ultimate moult like the female. Haplopelma sp. "aureopilosum" is "unofficiell" described by Volker von Wirth, if I'm right.

 

[morda]

It's still "unofficial". Hmm. when it will "official"... ???
This male looks like H. sp "aureopilosum" male. I saw many pictures of this species.
You'r crossbreeding them? Brother and sister..? Hmm, spiderlings may be more weak.

Sadly... I have no idea... But there are some rumors flying around of "Haplopelma vonwirthi"... a new species, or just the current name of "aureopilosum"?!

I'm not sure if they are from the same mother, but it is possible. We will see. Wish me luck!

I believe (not 100%) that Haplopelma vonwirthi is the name Dr Schmidt has given to what we call Haplopelma Sp "Vietnam" now he has described it, which im sure someone else was planning to do .

BTW: "looks" like the male that lead to slings of H.sp "aureopilosum" for me except it looks much better after the mating then that one did .

Edit here's the ref.

"Schmidt G. 2005, Haplopelma vonwirthi sp. n., eine neue Art der Haplopelma minax-Gruppe aus Südostasien (Araneae : Theraphosidae : Ornithoctoninae). Tarantulas of the World. Ausgabe 103, März 2005 : 4-12."

 

[morda]

So H. sp "vietnam" is being described and it will be named H. vonwirthi? When it will be the official name? We still need to wait with sp "aureopilosum" then.

 

[noname]

Here in Denmark people have begun to call their sp "Vietnam"s H. vonwirthi.

Cross-Breeding

Hi all,

Well, as an amateur biologist (BioEngineering major) I can tell you the chances of a bad trait showing up (yeah, I am also a Statistics major): 1.563%. Simply put all recessive traits have 50% chance of showing up in a child from each parent, assuming they both have these traits as recessives. Multiplying the probabilities, we get 25% - the chance of getting one "double" recessive trait that both parents share. Now, the chance of each parent having a recessive are the same, i.e. 25%. Multiplying 25%by 25% we get the chance of both parents having the same recessive trait = 6.3% (unless they are identical twins, then it's 25%). Then we multiply that number by the chance of getting a child with the double recessive trait => 1.563% - pretty low huh?

The problem is that the number of recessive traits that are deadly is unknown in any particular T, hence, this probability(1.6%), may have to be increased significantly as number of traits increases. As a pretty bad approximation, the chance that a T will have a nasty double recessive is n*1.563%, where n is the number of such traits possibly present in parents.

Since any successful mating results in quite a significant number of spiderlings, you will probably get some guys with nasty double recessives but most should do very well given good care, as statistics show anyway.

Fantastic pics as always Prizz.

Thanks Deschain, again!

Not sure what You mean, not because I'm stupid or something, just my english knowledge is limited a bit...

You mean the possible slings from this mating will be very weak? BTW, is this also called crossbreeding in the U.S.? As I said before, it is not even sure, if the are really brother and sister. I have to inspect that. I know the female is from the first hungarian "aureopilosum" breeding attempt. Where the male is from, don't know yet.

priZZ,
Well I really don't remember the technical term for mating brother and sister for non-human species.
Simply put, it is highly unlikely that most of the spiderlings will be weak. In fact, if the sac contains 1000 spiderlings, only 1.563% of them will be weak, on the average. That is, only about 16 spiderlings out of a 1000 will be weak. For these calculations I assumed that the spiderlings grandparents had relatively good DNA.
On practice you might have a number of bad spiderlings as high as 160 out of 1000. But this is unlikely.
You don't need to worry much.
P.S. I am sorry if my language got too complex - I am so used to it by now that it is hard to make it simpler.
P.P.S. I assumed that the parents were brother and sister; other wise, the chances of weak kids are even smaller; that is, better for you.

Brother and sister mating is usually referred to as inbreeding.

Breeding two different species is crossbreeding.

Many species of tarantula in the hobby are now deeply inbred with little sign of depression. Of course, specific recorded studies and observations are rare as this isn't the sort of thing that happens overnight.

Yes, the terminology you mentioned appears to be correct, as far as I recall. Deep inbreeding is AWESOME :worship: ! Just think about it: if we have hundreds of inbred generations, all the nasty gene combinations probably have eliminated themselves through death(or lack of mating) of their carriers. Hence, the population should be perfect in the long run.
On the other hand, "shallow" inbreeding results in relatively many deaths in first generations.
Conclusion: Inbreeding is good in long run but bad in short run.

Thanks for clearing this up guys! Now I know, what You wanted to say, speedreader, it was easier for me know! Sorry, fo my english, really, but had to read You answer 3-4 times, to understand it! My bad!

 

[speedreader]

priZZ,
It's ok - English was a problem for me too in the past.
I am happy to help.
Hopefully, your mating will bring excellent results!

I hope this as well. Thanks for Your patients and for the informations.

Take care!
