New Leo + Questions

[GeckoMandi]

Ok I got my leo tonight and she is very pretty, I thought I was getting a SHTCB , but turns out I had it backwards. My boyfriend went and picked her up for me and he failed to ask the 100 questions I had for the breeder, I couldn't go with him, wish I could have.

Ok she is a Rainwater *thought she was rainbow* Patternless Albino, now my boyfriend is friends with the breeder (chad) I think he bought from a few people here that post on this forum, anywho. He bred her for us ( note the scratches on her back ) bless her. Well he bred her to a SHTCB I have tried to understand the genetics I have some down pat, I"m wondering if the babies are going to be normals? Because the hypo tang is line bred?



Any help would be great.:main_thumbsup:

I'm hoping someone can better explain the rainbow gene. The only breeder I saw that has them listed on his morphs section is geckos etc, so maybe he can shed some light on them.
Also check the geneticswizard websight. You can enter in the genes of the parents and it gives you an outcome and percent prediction of the babies. I think from that cross though you're going to get a few poss percents of hypos tangs, a percent of het albino, not sure abou the carroting and patternless.

I thought she was rainbow, I'm loopy she is a rainwater paternless albino...

That is only valid if the mutation is recessive. Hypo, Tangerine & Carrot is not recessive.

So can anyone guess what the babes might be??

One day I'm going to learn the gecko genetics durrnit!!

 

[Golden Gate Geckos]

Your babies will be normals, possibly tangerines. Some of them would be het for patternless, some het for RW albino, and a few would be double hets... but the only way to figure out which offspring are the hets would be to prove them out through breeding.

 

[Grinning Geckos]

Wouldn't they ALL be double hets Marcia? The gecko that was breed is a homozygous LVPA.

 

[GeckoMandi]

Well I am so impatient I cannot wait to see the babies!! I am no expert at guessing the genetic stuff, so hopefully when they are hatched I can post them here and see what yall think.

As I said before I'm not trying to be a huge breeder and make profit, but I just like to know what I have.

Here's a quick way to understanding genetics. In Leo's there are three different types: line-bred, recessive, and dominant.
A recessive gene can only be expressed if you have both the recessive alleles (an allele is one piece of the gene, genes are two pieces, like AA, Aa, aa, etc.). The different strains of albino, for example, or recessive genes. So you need 'aa' in order for that gene to be shown (which is called the phenotype...what is visible). Since yours is a RW/Pat and she was bred to an SHTCTB, none of the babies will express the RW gene or the Patternless gene because the babies won't have 'aa' for both those genes, but would have 'Aa', 'aA', or something like that.
Line-bred traits (carrot tail, baldy, SH, etc.) I am still fuzzy on. My understanding is it's pretty much hit or miss. But I don't know exactly how these traits would be expressed when you breed with something that isn't the same. Probably significantly less in brightness I assume.
Dominant traits are ones that will always show when the dominant gene is present. So, for example, in albinos, since that is a recessive gene, any time you get aa, you get albino, but when you get Aa, rather than having a combination of the two, you show only the A (which would be normal type), because A is the dominant one. It will remain dominant. There's also Co-dominant, which would be two dominant traits expressed at once. But in any case, dominant genes are always expressed when the dominant allele is there. Which is why you'd have a significant amount of normal leo's in that pairing you have there.

Hopefully someone out there more versed in leo genetics can explain line-bred traits in more detail and in idiot terms because I"m still unsure how all that works. And if I goobered up anything in my explanation there, please correct me.

Selectively Bred / Line Bred / Polygenic mutations are the result of numerous alleles on numerous different loci. Which means that their is no way to tell (without expensive medical genetics mapping) what these alleles are, how they relate to each other or how they're inherited.

An example would be that the Tangerine coloration could be the result of 10 different sets of alleles that all have to align a particular way to produce the wide range of brightness that we see in them. When you cross those 10 alleles to another animal that does not have the matching 10 alleles, you're diluting the line and causing a less orange animal. This is all in theory, since we can not identify how this trait is reproduced.

Thank you TME. Very helpful

Thanks for the help, I hate to be so dumb about all this stuff I really do!

But I have been reading (daily) and trying to learn and every little bit helps me, trust that. lol

So now I wait for her to pop out those eggs, I cannot wait. I could care less what they are value wise I'm going to love 'em no matter what, I just hate trying to guess what something is, but then again that's why I have ya'll!!

Don't worry you will eventually get it, as long as you keep trying to learn. It took me so long to learn genetics and I am just now feeling like I actually "get it" And then it all seems so easy! lol
