HOW IN THE WORLD, do you understand gecko genetics, I'm so beyond confused

If there is a place that explains it that'd be great or maybe you can answer my questions!

What on earth is RAPTOR and APTOR

What is Het? Heterozygous, well what does that mean I forgot kind of

What is the percent mean?

How come you don't want to breed to tail kinked moms?

What are engimas, besides the obvious answer, a puzzle. What makes enigmas..enigmas?! and WHY on earth are they so darn exspensive!

Those are a lot of good questions, some with simple answers and some with not so simple answers. I think a good start would be to read through the "morphs and genetics" section on this forum, to look up some of the terms (like "heterozygous") and to look at the leopard gecko wiki (http://www.leopardgeckowiki.com/wiki/index.php?title=Main_Page). Once you do that, a bunch of your general questions will probably be answered and you can ask more specific,focused questions here, which people will be happy to answer.

Hey thanks so much !

it´s like math you just have to learn it

I`m just lucky Genetics came as a second nature to me. I would recommend checking out the Leopard Gecko Wiki but if you have anymore questions just feel free to post them here.

I'll answer the what is a het question.

Genes come in pairs, like socks. If the two genes in a pair are the same, the gene pair is homozygous. If the two genes in a pair are not the same, the gene pair is heterozygous. By extension, the gecko with that gene pair is also heterozygous (het for short). All gene pairs are either homozygous or heterozygous.

Usually a heterozygous gene pair is made up of a normal gene and a mutant gene, but usually is not the same as always.

A heterozygous leopard gecko may or may not look normal. That depends on what mutant gene is present.

Good luck.

I did gentics last year.....I never really understood it lol. It's just so complicated. I understand the use of the punnet square. So a heterozygous would be a Hh and a homozygous would be a H so heterozygous is the recessive trait and homozygous is the dominant or wait is it the other way around...So confused

Oh I need an example

Say you have a blizzard 66% het for temper albino and you cross it with a normal leopard gecko 100% leopard gecko what would you get? what would be the ressecive and what would be the dominant and so forth

Genetics is as complicated as the following problem:

John has two red apples and gives you one. Mary has two yellow apples and gives you one. What apples do you have? Answer: one red apple and one yellow apple.

John started with two red apples. The apples are the same color. Therefore, that pair of apples was homozygous.

Mary started with two yellow apples. The apples are the same color. Therefore, that pair of apples was homozygous.

You have a red apple and a yellow apple. The apples are not the same color. Therefore, that pair of apples is heterozygous.

In your Hh gene pair, H is not the same as h. You are right when you wrote that Hh is heterozygous.

"... and a homozygous would be a H ...." There is only one gene here. One gene does not make a gene pair, which requires two genes. H is neither homozygous nor heterozygous. Pity it; it's just a poor little singleton, standing all alone in the rain, without anyone to care, and likely to end in an unmarked grave.

If another H comes along and they make an HH pair, then the gene pair is homozygous. If we find an hh gene pair, that pair is also homozygous.

Clear as mud? I'll get back with dominants and recessives later.

Click to expand...

"66%" states the chances of that animal being het. In recessive mutations (like blizzard), you can't tell apart heterozygous animals from normals, because they have a normal appearance.

For example, if you bred two normals 100% het blizzard together, you would get 25% homozygous blizzards, 50% normals het blizzard and 25% homozygous normals. Since you can't tell apart the hets from the normals, all of them would be considered 66% possible hets.

Being recessive/dominat/etc only matters in heterozygous animals, in other words, when two different genes meet in the same gene pair as Paul stated above. We usually compare mutations to the normal gene.

When a gene is recessive, we mean that the appearance (phenotype) of the heterozygous animal is normal (blizzard is recessive).

When a gene is dominant, we mean that the phenotype of the heterozygous animal is that of the homozygous mutant animal (enigma is dominant).

I think this will be more useful that just telling you what would you get from that cross, specially if you know about punnet squares and all.

Wow still very complicated but much more understandable now, thank you guys so much !!!

I cant understand the genetics either.
Which is really lame of me considering I'm a chemist.
It seems like the more I read, the more confused I get!! :main_huh:

How I managed to get through school, who knows!!! :main_rolleyes:
