How often does a clutch hatch where more than one visiable morph male was placed with the same normal female and the clutch has hatchlings from both males? I'm not talking about males that carry multiple genes themselves, but single morph males.

For example, a breeder places both a mojave and a spider male in with one normal female at different times in the breeding cycle . . . how often do you get both spiders and mojaves in the one clutch? Does anyone do this intentionally? If so, what are the odds that both males' sperm fertilize the eggs?

Thanks

last year i use male pastel and male spider with the same normal female,i have 6 eggs,5 spiders and one pastel in the clutch.
but for the law of genetic another female normale with the same males give me all normal!!
so i enter in the 50% of the baby codominant!

Last year we rotated a Mojave, Spider and Pastel males to 3 females. Results were,

Clucth 1

7 eggs, 2 mojave, 1 spider, 4 normals

Clucth 2

5 eggs, 1 spider, 1 pastel, 3 normals

Clutch 3

9 eggs, 3 mojave, 2 spiders, 2 pastels, 2 normals

This breeding outcome was in fact to witness results breeding multiple males. Was fun watching different mutations hatch in the same clutch, I can only imagine the outcome if someone used Super males!

Thats pretty interesting. What if you where to breed a male albino and a male axanthic to a female double het snow. Would you be able to get a snow or would you only get hets albinos and axanthics? Would it be possible for both males to fertilize one egg?

1.0 Chocolate Lab
0.1 ?? Normal Ball python (yet different)
1.0 04 Het Albino
1.1 06 Het Albino
1.1 06 Het Pied
1.0 06 Pastel
0.? 07 Pos Het Albino (Momma has not laid the eggs yet)

I am glad someone else posted this question. I ask about the pastel fire/bumble bee from the same clutch. I was going to repost, but after the well writen and informative reply I got I figured what more could be said. As for your question, I think you would get some albinos, some axanthics and a bunch of 100% hets for both morphs and possibly some double hets. But since the hets would all look normal your quess would be as good as mine as to whos who. As for the single egg fertilzed by two different sperm I am not positive, but I think that would be the only way to produce a snow from that breeding.

I didn't think that it was ever possible for 2 sperm to fertilize one egg.

genes only pair up not trio up, correct?

Brian, WOW! Do you continue to pair multiple co-dom morphs with one female to obtain these mixed clutches?

Thanks everyone for your replies.

Yes, you rotate as many co-dom males as you want and odds are good that many of those co-doms will hatch in the same clutch.

Unfortunately we cannot pre-determine the exact moment of fertalization shortly before or during ovulation and so, having multiple males copulating a single female a few weeks before ovulatiuon is the key!

Thats whats fun with dom and co-dom mutations, not so easely done with recessive mutations
