Ok... I purchased an `04 Female Blaze Phase Goini earlier this yr. from a breeder on the east coast... I contacted him about purchasing a male and I had some questions

the most important question: "Have you ever produced a Het. Blaze phase?"

to my surprise he told me NO. he said that when he bred him pair they produced all blaze phase Goini (every time they've bred) some were just "uglier" than the rest, but all Blaze Phase. Now this has my mind going crazy! if recessive why not one het?

I'm not very good with genetics so if someone can explain how this is possible I'd really appreciate it

Thanx

If the breeder bred Blaze phase to Blaze phase...Yes all the offspring would be Blaze phase as is any recessive trait.
But...I do not know if Blaze phase is recessive...i would think so if all offspring from such pairing are homozygously Blaze phase.

ok... i'm still confused

Albino/hypo/Axan are all recessive right? so if i bred 2 Amel snakes together won't i get Majority Amel and a few (maybe one) normal het. from the pairing?

i know with double morphs you'll produce all 2x morphs when bred together (Snow x Snow = all Snow) this i can grasp... so what if the Blaze is really a 2x Morph????

I'd like some more input on this

Thanx

No...
If you breed two Homozygous (amel) snakes together theoretically ALL offspring will be homozygous (amel).
Hets are produced by breeding a homozygous snake to a normal, wild type mate. Amel to Normal will produce all 100% heterozygous offspring. Breeding these offspring to one another will produce homozygous offspring along with possible het offspring.
If you breed an amel to an axanthic you will get all normal double het offspring. Breeding these two you will produce normals that are possible het for both, amels possible het for axanthic, axanthics possible het for amel and 1 in 16 will be a snow....
Check out Terry Dunham's genetics page...It will help you out ZF.

Recessive means that when a homozygous snake (amel) is bred to a normal it is not dominant...It is rather recessed or carried by the offspring....
Get it yet?????
Email me if you would like,

i know recessive means a trait that is carried and not expressed in "normal" offspring like the striped gene in cali kings is dominant while lavender would be recessive... i got that

I just had to go back 2 HS on that one... i had to draw a Punnett Square

homozygous recessive x Normal= 100% hets

100% het. x 100% het = 1/4 homozygous recessive

homozygous recessive x homozygous recessive= 100% recessive trait

come to think about it if i thought this through some more i would have save myself from this "easy" answer

Thanx John

UR Welcome Zenny...
Now you wanna talk about Triple het to triple het pairings or maybe some co dominant traits....If so ask some one that knows better than I.....LOL
And really..Check out Terry's genetics page...It WILL help you out more if you have any more questions.

do you have a link to Terry's site or genetics page

Thanx in advance

Also there is a link in the sponsors up above the posts......LOL

is the Blaze Phase a morph?? i believe they are selectivly bred normals? i may be wrong , but any way you have a good lookin animal there.Chris

Thanx for the complement... she's a great animal.

Now:

Selectively Bred Normal? i don't think they are... i say those Hi-REDS Brandon produced last year are an example of really Nice selectively bred "normal" Goini

i think the name Blaze is sort of misleading for this trait.

~ZF

Well....
The name actually states it is a PHASE and not a morph.

Just like dark phase alterna or mexicana.
I still don't know if Blaze phase is a single recessive trait or not....Maybe someone else will tell us....

thats what i was thinkin, i still gotta post some hi red goinis i have, NOT Blaze acording to me,keep up the good work on themChris see you in Daytona............C
