another stupid genetic question, sorry...

cmsuphoto May 23, 2004 07:33 AM

this one isn't the silly "what would I get if I cross a black albino with a red albino" question. This one actually is a little harder, and it's only like that because I didn't want these two snakes to breed, but they did...here goes...

Male was sold to me as a double het, anery and amel. The female came from my cluth two years ago, ghost and hypo mix, meanin' in a way, she's double het too. ANyway, neither snake is showing anything but normal, so that's cool, but here's the question. Since ghost is hypo and anery mix, that means she has to be het for both those, and the double het (anery and amel) male, I would get 25% anery? Sad thing is she only laid 9 good eggs, so I probably will get all normals, but even then, can I be certain that the normals are het for anything, or will they just be good ole normal corns? The way my luck has been going, I'm gonna get something absolutely crazy, like last year! Any experts out there that can help, I'd appreciate it! They should be hatching in the next few weeks, and I'm just curious as to what I might get. Thanks in advance!

When you say "ghost and hypo mix", do you mean a ghost bred to a hypo? That would have given you all hypos het for anery.

That is what that ment for the other one, a ghost mom and hypo dad is the pair she came from, but wouldn't the genetic recessive anery gene in both snakes make some of the babies come out anery?

Hypo x ghost has to produce all hypo babies. My guess is that another male got in his licks with that ghost, too.

As for the current mating you are asking about, theoretically you can expect 25% of the eggs to produce anerythristic babies. And you have a 92% chance of getting at least one anerythristic baby. IMHO, pretty good odds. Have fun!

Well, I know the female and male were definately ghost and hypo, I just don't see a whole lot of hypo in the offspring. Faded black, yes, definately lacking distinct black rings that look amazing in okeetee, but there is some black there. However, there's no way a different male got ahold of the female, so genetically speaking, I konw wassup with these babies. But, I was just making sure I would get some anery babies, if possible. Thanks for the heads up!

Paul,

When you say, "Hypo x ghost has to produce all hypo babies," aren't you assuming that the ghost and hypo are homozygous for the same form of hypo there? What if the hypos were incompatible?

"IF" that were true, then the female having been bred now would be normal het for anery and double het for two types of hypo. If bred to a snake het for amel and anery, the following would be statisically produced:

75% normal (each one with a 66% chance of being het for anery, a 50% chance of being het for amel, a 50% chance of being het for EITHER of the hypos, and a 25% chance of being het for BOTH hypos)

25% anery (each one with a 50% chance of being het for amel, a 50% chance of being het for EITHER of the hypos, and a 25% chance of being het for BOTH hypos)

But there's really no way to know until further breeding trials are accomplished, and it doesn't sound like this pairing was ever intended in the first place. So, the owner will likely never know for certain.
