PostSubject: Parthenogenic T. Stigmurus?   12/28/2011, 11:05 pm

I was wondering, if T. Stigmurus are parthenogenic and 9 out of 10 or 99 in a 100 are females how would you know if you had a male. I'm in the process of acquiring 2 females and I would like to increase the genetic variability by using a male to breed with them. Does anyone have a male or has anyone ever seen a male?
Thanks in advance!!!

Yes, they are parthenogenic. Just like Hottentotta hottetotta, those in circulation of the hobby are mostly females. So far i've yet seen a documentation of a T.stigmurus mating pair, not even a pic of a male. Anyone has leads to it?

I'm no expert on genetics, but I believe all stigmurus in the hobby are female just from the basic knowledge that without breeding with a male, you can't get the male determinant chromosome. Parthenogenesis is kind of like cloning, so if you have a female egg self fertilizing to create the zygote, you only have XX gender determinant chromosomes present, not XY.

Very clear and good point raised by Envyizm.

I've been thinking about researching more on T.stigmurus but just couldn't find the time yet. So far i'm only concentrating on nuturing them up to adults so that they can start popping.

I remember seeing pictures of male H.hottentotta (HH) mating with a female but never with T.stigmurus. I have heard of male HH in the wild, wondering if its really a total different story with the latter.
