    A couple of genetic questions

    I'm not surprised that you get lost. I figure there are around 4 gene pairs involved. Which makes Punnett squares of up to 216 boxes. Have I mentioned before that only masochists do Punnett squares with more than 2 gene pairs? :main_laugh: A branching system needs half the time (or less) that...

    Tug snow X Mack snow question...

    I looked at leopardgeckowiki.com, too. I couldn't find an answer to the original poster's question there. Putting two recessive mutant genes in the same animal could prove something, but TUG snow and Mack snow are not recessive mutants. Putting those two mutants in the same animal proves...

    Morph List

    Doug, if you can edit the morph descriptions on leopardgeckowiki.com, please correct the information it has on RAPTORs. It's my usual one-stop source for leopard gecko genetics.

    Morph List

    Determining whether a mutant gene is dominant, codominant, or recessive to the normal gene involves answering three questions. 1. Does a gecko with two mutant genes look like a gecko with two normal genes (yes/no)? In all cases, the answer should be no. 2. Does a gecko with one mutant...

    Morph List

    Any effect that the stripe gene or genes has in combination with the phenotype of other mutant genes is interesting. Trouble is, the stripe mutant gene or genes are dominant, codominant, or recessive to the normal version of the gene. Interactions with unrelated mutant genes just aren't relevant...

    Morph List

    For what it's worth, I've never heard the term "incomplete recessive" before this thread. In my opinion, multiplying categories just multiplies confusion. I think would be better to dump the term and classify the mutant as recessive, codominant, or dominant (whichever seems closest).

    Morph List

    Two genes, A and a, make three gene pairs: AA, Aa, and aa. If an Aa animal looks like an AA animal, then gene A is dominant to gene a, and gene a is recessive to A. That's how the textbooks define it. The pro geneticists classify one gene as the wild-type or normal gene and the other as the...

    A little genetic help needed.

    A raptor is selectively bred for orange besides having three recessive mutant genes - Tremper albino, eclipse, and patternless. An albino het raptor would be heterozygous for eclipse and patternless. Your babies have a 50% probability of being het eclipse, a 50% probability of being het...

    bell enigma X SHTCT?

    According to the files on www.leopardgeckowiki.com, the Bell albino gene is a recessive. The enigma mutant is a dominant, but no homozygous enigmas have been produced. Therefore, a Bell albino enigma gecko has a pair of Bell albino mutant genes and an enigma mutant gene paired with a normal...

    silly question

    This cross involves two gene pairs in each gecko. A Bell albino has two normal genes in the gene pair that is equivalent to the gene pair where the Mack snow gecko has a Mack snow gene and a normal gene. And the Mack snow gecko has two normal genes in the gene pair that is equivalent to the gene...

    Trying to make Cremsicles

    The page at the link (above) says, "Cremesicles are top notch four and five star quality high contrast, white, bright yellow, and orange super hypo Co-dominant snows." That means that the geckos have a pair of hypo mutant genes and a Mack snow gene paired with a normal gene. And they are line...

    Het question

    We all start out ignorant. All pairs of genes are either homozygous or heterozygous. Homozygous = the two genes in a gene pair are the same. Examples - two normal genes, two Tremper albino gene, two Mack snow genes, two A blood type genes (in a human). Heterozygous (slang het) = the two...

    Genetic info for diffrent species?

    Which species? Some are known better and have more mutant genes than others.
