breeding morphs

[Cold-B-Hearts]

hey guys,
im abit confused when it comes to breeding morphs, i dont understand the whole het and everything, a good explanation would be appreciated thanks.

feel free to post pics of your morphs

het means the snake has the genes but doesnt show it

 

[killimike]

Why did you make two threads?

And someone asks about 'het' literally twice a day... As per the recent discussion, het does not actually mean that a snake has the genes but doesn't show it. See the explanation in the other thread you started.

 

[Cold-B-Hearts]

ok so say you have a het darwin carpet and a albino dawin carpet half the hatchlings will be normal half albino
but if you had a dawin carpet and a albino dawin carpet all the hatchlings would be normal
what about a het albino?

Um yes it does.. If the animal carries the gene and shows it it is regarded as co-dominant or dominant

sorry about the two treads, i dont have much internet and no one was replying on the other thread and mroe people 'browse' genral descussion

Says who?

 

[Dannyboi]

You know that annoys me when you learn genetics at school Co-dominant refers to sharing dominance but with reptiles every time I read or hear Co-dominant if refers to it being Completely dominant.
Heterozygous animals can show a trait but may not it depends on the genetic trait.

In what case do you hear of co-dom being used to describe complete dominance?

 

[CamdeJong]

Dominant genes are those which override others, co-dominant genes can both be represented in one organism. An animal can carry a recessive gene and show it if there are no genes to dominate it, this doesn't make the gene dominant. Liam, the easiest way to get the genotype/allele concept is by making a table with the parents' genes as the axes and combining the alleles. Examples of this are probably on the net.

Nuh huh it doesn't! Dominance is completely different to homo/heterozygous, you have confused the two.

I read it on most Jag info sites.

Any morph that has a visual het is reffered to as co-doiminant to my understanding correct me if im wrong but hetrozygous means the recesive gene is masked (not visual)?

There's the mistake. An allele can be dom, co-dom or recessive, and an animal can be homo or heterozygous at a particular gene. They are separate characteristics.

Here is one of the million threads on this at random:

ok i think im starting to get it. so a albino is a co-dominant gene but will override the het gene producing 50 50 ill do some more reseach but whenever i seach anything ball pythons and corn snakes always come up

 

[jamesbecker]

het x het = 25% albinos 75% hets
albino x het = 50% albino 50% het
albino x albino = 100% albino
normal x albino = 100% hets

 

[waruikazi]

I read it on most Jag info sites.

The JAG gene is not dominant, it is incomplete dominant or co-dominant depending on who you ask. The homozygous form of the JAG gene is a leucistic.

Any morph that has a visual het is reffered to as co-doiminant to my understanding correct me if im wrong but hetrozygous means the recesive gene is masked (not visual)?

Co-dominant, dominant and recessive describes how the gene is expressed not wether it is carried or not. Although you can assume that if an animal is described as one of those terms that it is a carrier.

 

[Ramsayi]

het x het = 25% albinos 75% hets
albino x het = 50% albino 50% het
albino x albino = 100% albino
normal x albino = 100% hets

back to school for you!

no, the albino gene is dominant (might be recessive dunno), that needs 2 of the same gene for it to be expressed.. if a snake is said to be a het, it means it carries one set of the genes

 

[killimike]

ball pythons and corn snakes work the same way Liam, at least as far as it matters.

Albino is recessive, and there is no such thing as a het gene. Please read some threads on here, then the corns won't bother you
