I have an albino checkerd garter and an oregon red sided garter, they are to young to breed right now, but i was just wondering what would be the out come.

Are there genes codominant or incomplete domanice?

There wont be any albinos unless the red is a heterozygous, right?

Like if AA is the domanint gene for non-albino and aa is the recesive for albino, their babies would be

Aa, Aa, Aa, Aa- and because they only have only recesive there will be no albinos.

Or If AA is domanint gene for non-albino but OO is also domanint for albino their babies would be:

AO, AO, AO, AO--so there would be mixed scale patterns because of incomplete domanice.

Thanks for any help

I believe that you are academically correct. The babies would all be Aa where A is the normal gene and a is the recessive albino gene. If your Red-Sided is het, Aa, the babies would be Aa and aa in theoretical equal percentages. I doubt that your Red-Sided is het however. Another thing to consider is that you are dealing with hybridizing here. I am not aware of any interbreeding between Thamnophis marcianus and Thamnophis sirtalis concinnus. At best you will be breeding for several generations to get the results you want. Your best bet is to acquire another Thamnophis marcianus either albino or het, and breed within the given subspecies you wish to work with. The same with your Thamnophis sirtalis concinnus. Are you certain yours is an Oregon Red-Spotted as opposed to either a California Red-Sided or a regular Red-Sided?

Thanks for the info, that is what i was thinking, I highly dought he is het. here he is...

Nice little concinnus!

There may be albino concinnus out there (it's a big world) but I've never heard of any. Doubtful you'd have a het and not know it.

Hi

I hope you see this, since it has been awhile since you posted.

You are asking about breeding snakes of two different species.

Therefore, the genetics of this possible cross CANNOT be known, since the two species you are wanting to cross might not even be able to produce live offspring.

Deformity, genetic problems, infertility, and health problems are all possible. It is also possible that you might get live offspring, and someone may purchase them from you. If so, and if that person is unethical enough to release their snake, or their snake is smart enough to escape... the damage to the environment could be devastating, as the snake could cross with wild garters and taint the gene pool of the species it crosses with.

I would advise that if you want to do some interesting crosses, with different traits or morphs, that you stick to one species... and I would suggest you visit the website of Scott Felzer, who is a sponsor of this forum. He will be able to advise you as to the genetics of the two species you own, and enable you to choose one for a breeding project.
