Co to za gekonki:

ok zmienilem a drugi to jaki musze wiedziec szybko

A czy nie jest tak że każdy chciałby mieć jakieś pieniądze ze swojego hobby? Mój znajomy ma hodowle i próbuje od 7 lat otrzymać Super Enigme jak do tej pory bez skutku, a ja chciałem jakiegoś fajnego samca dla moich samic Samice mam Paternless i Super Hypo Tangerine Carrot-Tail, chciałem dobrać dla nich samca żeby mi jakieś fajne młode wyszły.

A ten?

podobno są ale zazwyczaj młode padają po paru dniach, a nawet w fazie embroidalnej.

Here we have a dominant mutation in Leopard Geckos, and a very exciting mutation it is! Discovered by Mark & Kim Bell, prodigious reptile breeders indeed, and initially marketed and named by Kelli Hammack in 2005.

Specimens exhibiting this trait develop spots and patches of coloration in unusual locations, yielding a "calico" appearance as adults. Between the unusual appearance and the unusual dominant mode of inheritance, the exact nature of these geckos was initially something of a mystery, or enigma, hence the name.

Sadly, the Enigma trait appears to be linked to a defective gene which causes behavioral disorders. Thus far, all known specimens exhibit varying degrees of head-trembling, odd 'circling' behavior, and spastic motion - especially when excited. This seems quite similar to cerebellar hypoplasia in mammals, although it's unlikely any studies will ever be done with the geckos to confirm this due to financial constraints. We've purchased several specimens from breeders claiming they are free of this problem. But careful observation has revealed it to be present, just greatly reduced in severity, and all offspring from these specimens have exhibited the behavior. Test breedings to non-Enigmas have resulted in the production of large numbers of both Enigmas and non-Enigmas. ALL Enigmas have exhibited the trait, while NONE of the non-Enigmas have shown it - conclusively demonstrating that the behavior is linked to the Enigma trait.

Since the mode of inheritance of dominant mutations is new to most Leopard Gecko keepers, I'll attempt to explain it here in some detail.

With regard to the Enigma mutation and it's effect on appearance, Leopard Geckos can exists in three possible genetic states: Normal (no mutated alleles present), Enigma (one mutated allele present) and Enigma (two mutated alleles present).

1) Normal specimens (no mutated alleles present), are of course, just that - completely normal in every way. They exhibit no characteristics of the Enigma mutation, nor can they be heterozygous for Engima.

2) Enigma specimens (one mutated allele present) can be easily distinguished as hatchlings by their lighter overall appearance, and quickly develop the beginnings of the spots and blotches typical of adults. Strictly speaking, these are in fact heterozygous and typical rules of inheritance apply when breeding them - the only thing different here is that such heterozygous specimens can now be spotted visually, something that cannot be done with simple recessive mutations!

3) Enigma specimens (two mutated alleles present) are suspected to be of identical appearance, as no obviously different specimens have appeared from breedings between two Enigmas thus far. As of this writing, it is unclear whether specimens proven homozygous for this trait exist as breeding trials will be required to identify them and clarify this issue. This author suspects this to be a lethal gene, causing specimens with two copies of this allele to fail to develop in the egg. This is born out by limited breeding experiments in which a higher than usual percentage of eggs have failed to hatch. Results are limited and far from conclusive.

Understanding the mode of inheritance and the predicted outcomes of various crosses can greatly simplify sorting out the results. Perhaps the following will help and is based on the presumption that all Enigma specimens possessing two mutated alleles will fail to hatch, dying as embryos:

Normal x Normal yields all Normal offspring.
Normal x Enigma (one mutated allele present) yields half Normal, half Enigma (one mutated allele present) offspring.
Enigma (one mutated allele present) x Enigma (one mutated allele present) yields 1/4 Normal, 1/2 Enigma (one mutated allele present), 1/4 Enigma (two mutated alleles present) offspring. These homozygous specimens are suspected to die as embryos and never hatch.
