Question about Dominance

[endrien]

I know for sure that my girl is Hypo Tangerine, I am not so sure on if she has any Hereditary genes. I immediately fell in love with Albinos , but it is a recessive trait isn't it? Meaning if my Hypo Tang does not have het Albino, Hypo will take dominance with the other being het?

If this is the case is there any way to tell if my Hypo Tangerine has any het albino?

also, If I paired her with a Tangerine, the outcome would be a Possibly bald carrot tail tangerine? Or would it be a Hypo?

Thanks

yes, without knowing the het you would only get het albinos, and the only way to find out if your gecko is het for albino is knowing the parents or test breeding. Albino is a recessive gene so even if your hypo tang is het only 50% will be albino and the rest will be het.

You will probably get other answers....but from my reading you can't tell a het albino unless you know what it is. There are multiple albino genes and they are not compatible.. so if you breed a bell and a tremper you get one or the other but you can't tell which one you actually have. If its a bell and you breed it back to a bell.. well you get bells, but if you breed it to a tremper then you will again get either a bell or tremper without being able to tell.

You have to know what the parents were as far as the albino part goes.

Hypo has to do with the spot number... super hypo.. no spots.. is (according to the LeopardGeckoWiki) line breed, so it just depends on the spot number of the mate. Find one with little to no spots and hope you get lucky. Carrot tail is also line breed, so if yours doesn't have any carrot tail then you'll want a male with as much as you can find and afford.

I should probably add.... you can find out if she's albino in general... you just won't know WHICH albino. Though some breeders like to guess for the unknowns.

I don't want to even go there again with unknown albinos....

I may try to get a male a female tremper and breed them, as I love their look. I just wish my male tremper wasn't possibly double het albino as I love his coloring. Already started looking for a home for him though.

Yea, the albino thing can be a pain. I would love to breed my female enigma because she is pretty AND doesn't harldy show any enigma side effects, so it would be very interesting to see if that trait carried over into the offspring. However, she is unknown albino so I am not going too.

Albinism (which, in leopard geckos, includes all three strains of albino) is a recessive trait, it can only be fully expressed if a gecko has two homozygous (same) copies of the albino gene.

Even though Tangerine and Hypo are polygenic traits, they are nonetheless line-bred traits that stemmed from the Normal leopard gecko, which is dominant. So therefore, Hypo and Tangerine (if the gecko carries no additional hets) will act dominant when crossed with albino. While line-breeding results in traits or characteristics becoming more defined or improved, it doesn't change the basic genetic material of an animal (whether the animal is dominant or recessive, excluding the possibility of polygenic traits coming into play).

You can never tell what an animal is heterozygous for based on the phenotype (outside appearance), because that information is stored in the animal's genotype, or genetic material Let me use a Tremper Albino het Eclipse for example. The gecko has the gene for making red eyes, but does not outwardly express it. It can, however, be expressed in the offspring if paired appropriately.

EDIT - I had not seen your other thread in Show of Your Leos when I had posted all of this ^ but I'm editing this post because I've seen it now. I would not breed that gecko since the genotype is unknown. I'm sure you've heard this already, but double albino hets are serious in the gecko community. They can create an absolute genetic mess if bred. That gecko should be a pet only, and not ever a breeder because of the unconfirmed genetic material. Everything I stated above with crossing Hypo Tangs only applies to pure Hypo Tangs that carry no hets. Sorry for all the information, but I hope you'll get something out of it...
