Sperm retention?

Rhacophile Feb 13, 2005 08:01 PM

Ok I asked this question a while ago but no one answered me.
If a female has been breeding with a male and say she lays a clutch by him, what are the chances if I pair her up with a differnt male for the next clutch she will be retaining sperm and not actually laying eggs fathered by the new male? I have been wondering this because I like to switch male often so as to see all of the differnt combos I can creat.

Separate the female from all males for at least a month to see if she's still producing eggs. If your female goes four weeks without laying another clutch, I'd say she's all cleared out. But I have limited experience with separating females having only done it once, and I'm pretty sure they produced at least one more clutch - maybe two, but the second set went bad.

I think Anthony said he's had one produce eggs up to four months later?

Thanks for trying to clear things up, But I wonder? Do you think if you did pair her up say a week later, because of the amount of mating that will be going on untill she lays that the new sperm woul overide the old? I hope you understand what I'm trying to say. Anyway everyones thoughts are appriciated, yes even you Anthony.

...you'd never know which was the father. We let ours finish any egg laying, then put in the new male. So any new eggs represent the new male with certainly.

As for the new one beating out the old, probably not, but maybe so, again who knows? But any of the available sperm could potentially fertilize the ova.

Yeah that's about what I figured, but not exactlly what I wanted to hear. I just don't have enough females to really see the true patentions of all my males within a short amount of time. I guess it's just going to have to be a waiting game. Thanks for all the comments.
