So how did this happen?

Breeding was my G-Stripe male to a CBB Normal female. Did the same pairing last year resulting in 5 good eggs: 4.1 Normal Hets.
Same pair again produced 5 eggs this year, but 3 went bad early on. The remaining 2 looked fine until 5 days ago when 1 completely collapsed. The one good remaining egg pipped today (normal Het) so I cut the collapsed egg and found this:

Obviously a perfect G-Stripe fully formed dead in the egg. Besides being bummed at losing what looked like a very nice animal, how did I get a Homozygous G-Stripe?
I'ver heard of Parthenogenisis, but wouldn't that only happen if the FEMALE was the Homozygous Morph?

They should have all been hets! I guess you got lucky! Well you would be lucky if it survived!

wow sucxh a beauty too. so sorry that happened.

If the baby didn't receive 100% of the alleles of the normal then the stripe could be expressed. I am guessing some pretty major genetic defects in the way of missing chromosomes and such.

Where did you get your female from? The only explanation I can think of is she is actually a het and you missed the odds last year.

Pretty interesting. I had a buddy who bred 2 albinos together this year and got 4 albinos and 2 het's out of it? Not sure how that should happen either out of albino to albino breeding. To bad it died. Oh well now your het's held back from last year will hopefully be up to weight for this year.

It is possible that one of the albino was actually a paradox, but instead of mixed colors it got the absorbed twins "Parts".

Genetic stripes are weird, Ralph Davis had the same thing happen to him a few years ago, a Dead premature G-stripe looking snake in the egg from a pair that should not have dont that! So, I would not say that the female is a het, yet at least.

Aww to bad it died :(

I am definitely NOT calling her a Het. That's what leaves me so puzzled. She was from a breeder in a lot of 20 normal CBB females (all supposed to be codom siblings-which makes sense) The price on G-Stripes and Hets was still pretty high 4 years ago so I con't believe anyone would package up a prized Het female in a group of "normal" females.

She could be an unknown het, the only way to prove that, though, would be to produce viable offspring that are g-stripes from her.

However I would assume that either the genes were read incorrectly due to some defect in the RNA polymerase causing reading to be done incorrectly or perhaps an error with the dna polymerase in the female causing certain genes to not be copied correctly.

Or perhaps g-stripe is just a strange trait that occasionally is expressed dominantly and leads to fatality.

She was purchased in a lot of 20 CBB females from Edensnakes. They were all supposed to be siblings to their CoDom breedings.

it would definitely be awesome if she was in fact het for g-stripe tho:rolleye2:

so sorry for your loss.

Very sorry the baby didn't make it :( I tend to agree with Egapal, though, in hypothesizing that there may have been a chromosomal defect that caused this. If the baby only got one copy of a certain chromosome (obviously the dad's copy), it would be lacking the normal, functional protein from mom that would give it a normal appearance, so it looks like a homozygous genetic stripe even though it only has one copy of the "stripe" gene.

Unfortunately, it looks as though that missing chromosome also prevented it from completing development sufficiently to emerge from the egg :(

She was probably a Possible Het that someone threw in to make an even 20 lot.

I don't think that she was a Poss. Het that someone "threw in", but maybe the breeder I got her from bred a Pastel or Spider or some other CoDom to a CH import that they didn't have any idea was a Het. G-Stripe (prob. still don't know to this day) so all of THOSE babies were Poss. Het. G-Stripes without the original breeder knowing it. At least that is what I'm hoping- that I just missed on all the babies last year, and I got a really cheap Het G-Stripe female....

Try again when she's ready. If you produce a g-stripe then you have a het. If not, you had a freak genetic occurrence.

Aw, that sucks, poor baby :(
