Reptile & Amphibian Forums

I am pretty new to breeding boas and have been trying to figure out the punnet square thing to no avail. I'll let you know what I have and maybe you could give me a good route to go to pair them up.

1.0 Albino
0.1 Normal
1.0 Anery (66% Het Snow)
0.1 Hypo (66% Het Snow)

Any help on this would be great.

Thanks,

0.1 Hypomelanistic Boa-66% Het Snow (Sunset)
1.0 Albino Red Tail Boa (Cooper)
1.0 Anerytheristic Corn (Casper)
0.1 Snow Corn (Snow)
0.1 Miami Phase Corn (Lily)
1.0 Green Iguana (Butch)
0.1 Citrus X Sunfire Bearded Dragon (Fury)
0.0.5 Emperor Scorpions (Too many to name)
2.0 Uromastyx Geyri (Tobasco and Dijon)

>1.0 Albino
0.1 Normal
1.0 Anery (66% Het Snow)
0.1 Hypo (66% Het Snow)

The Anery (66% Het Snow) has a 66% chance of being heterozygous albino and a 33% chance of not being het for anything.

The Hypo (66% Het Snow) actually has the following probabilities:
4/9 heterozygous albino, heterozygous anerythristic
2/9 heterozygous albino
2/9 heterozygous anerythristic
1/9 not heterozygous for either albino or anerythristic

You can make 4 matings with these snakes:
1. albino x normal --> all normal-looking babies, heterozygous albino

2. albino x hypo. This is a test cross to see if the hypo is heterozygous albino. No anerythristics would be expected to come out in the babies, so I will skip that mutant. There are 2 possible answers.

albino x hypo, heterozygous albino -->
1/4 hypo albino (sunglow)
1/4 hypo, heterozygous albino
1/4 albino
1/4 normal looking, heterozygous albino

albino x hypo (not het for albino) -->
1/2 hypo, heterozygous albino
1/2 normal-looking, heterozygous albino

3. anerythristic x normal --> all babies look normal and are heterozygous anerythristic.

4. anerythristic x hypo. This is a test cross for whether the hypo is het anerythristic. There are two possibilities:

anerythristic x hypo, heterozygous anerythristic -->
1/4 hypo anerythristic (moonglow?)
1/4 hypo, heterozygous anerythristic
1/4 anerythristic
1/4 normal looking, heterozygous anerythristic

anerythristic x hypo (not het for anerythristic) -->
1/2 hypo, heterozygous anerythristic
1/2 normal-looking, heterozygous anerythristic

If any albinos or sunglows come out of this mating, then both the anerythristic and the hypo are also het albino. That would be a pleasent surprise, and the nonalbino babies could be rated as 66% probability het albino, too.

The first year I would mate anerythristic x hypo and albino x normal. Because you might get lucky and prove both the anerythristic and hypo are heterozygous albino. The second year I would mate albino x hypo and anerythristic x normal.

On the other hand, I'm not up on prices. It might make better economic sense to try for sunglows first.

You could put both males with both females, but that wouldn't prove out any of the 66% probability hets.

Hope this helps.

Thank you so much. It's been driving me crazy trying to figure it out.

So I wouldn't be able to produce any ghosts from my Anery x Hypo? I haven't picked up my anery yet. I was going to this weekend. I am also thinking of getting a female anery to breed with the albino to make snows. Is there a het that I should be looking for? I just want to make sure I'm getting the right snakes to get some nice morphs. Thanks again for all of your help.

>So I wouldn't be able to produce any ghosts from my Anery x Hypo?

Sorry, I made a mistake. The baby from the anery x hypo mating that I marked (moonglow?) should have been ghost. So you can get ghosts from this mating if the hypo is heterozygous anerythristic. If not, you will not get ghosts.

>I haven't picked up my anery yet. I was going to this weekend. I am also thinking of getting a female anery to breed with the albino to make snows. Is there a het that I should be looking for? I just want to make sure I'm getting the right snakes to get some nice morphs.

To be a snow, a boa must get an albino gene from each parent and an anerythristic gene from each parent. If you get a female anery, try for one that is also marked "het albino" or "het snow". If such a female is not available, try for an anerythristic female marked "66% het albino" or "66% het snow". Mating such a female with your albino male would test whether she is heterozygous albino and whether the male is heterozygous anerythristic. He probably is not, but you might get really lucky and get a snow in the first generation. If the female is also het albino, you'd expect half the babies to be albinos. Worst case would be all normal babies, and they would be heterozygous for albino and heterozygous for anerythristic. Mating those babies together would produce 9/16 normals, 3/16 albinos, 3/16 anerythristic and 1/16 snow (expected ratios; actual ratios may vary).

Half the battle in producing morphs is knowing what you are starting with. After the first year's breeding, you will have a much better idea of your snakes' genetic make up.

Good luck.

Paul,
Thank you very much for all of your help with my boa project. All of my snakes are 06's so I have a good couple of years before I can give it a shot, but I wanted to make sure I'm getting the right matches to begin with. This forum is the best. All of you are a great help.

Thanks again.
