Reference for Compatible Genetics

[lizzy_troy]

I'm extremely new to bp genetics, but I am loving the research! So, please pardon any incorrect terms.

Is there a website that explains or lists what morph genes are located in same vs different loci? I hope that question made sense. What I'm looking for is a reference that would tell me if XYX gene would dominate or compete with ABC gene, or if the two (or more) genes would show up together. For example, I found a website that showed Punnet Squares for one set of genes and larger squares for two sets of genes, but they only used Albino and Axanthic for illustrative purposes.

I have read the basic genetics post, as well as many other "genetics 101" articles, so I have a decent grasp on the concepts.

I like this one;

And also his genetic calculator.

Thanks. I have checked out that site before. I guess what I'm looking for is more of the geneotype info, so I better decipher the phenotype info.

The link posted above is a list of all morphs known to be on the same locus, every other morph would be on a different loci, until proven otherwise.

Dominating has nothing to do with loci, it is just a comparison between the phenotypes of two genes, they can be on the same or different loci. Normally we refer to mutated genes vs wild trait genes, but you can compare mutations to mutations. Without opening the argumentative world of classification, lets just say It has everything to do with phenotypes and not much to do with genotypes.

what genotype info are you after? The genotypes don't really help with the phenotypes unless you already know the phenotype that is caused and that would be a morph by morph basis. Once you understand heterozygous homozygous and allelic stuff, you pretty much got the genotype stuff down as far as this hobby is concerned. I mean from there I would tell you that we have classification based off of the phenotype of the gene in heterozygous and homozygous form, compared to the wild trait versions.

	Heterzygous	Homozygous
Dominant	Visual change	Same visual change
Co-Dom/Inc-Dom	Visual change	Different visual change
Recessive	No visual change	Visual Change
Unproven Dominant	Visual Change	Unknown

or am I completely off base of what you are looking for?

The way I read the original post, the poster wants a table of gene sets with the same locus and the dominance relationships among each set ot genes.

In other words, lesser platinum, mojave and a number of other mutant genes (and one normal gene) have the same locus. Lesser is codominant to the normal gene. Mojave is codominant to the normal gene. Lesser is dominant to the mojave gene because a snake with two lesser genes is blue-eyed white, a snake with a lesser gene paired with a mojave gene is blue-eyed white (same as a snake with 2 lesser genes), but a snake with 2 mojave genes has some pigment on the top of the head and neck.

The lesser gene is codominant to the daddy gene because a snake with a lesser gene paired with a daddy gene is lighter than a snake with two daddy genes and darker than two lesser genes.

Now determine the dominance relations between the lesser platinum gene and the Russo gene, lesser and bamboo, mojave and the Russo gene, mojave and the bamboo gene, etc. Repeat with the other sets of genes. I don't have most of that information.

well lesser dominates over russo. I'm not quite sure what you would call bamboo vs Lesser since both homozygous version look the same as far as I can tell. mojave dominates over russo.

bout all I can answer from that.

Thanks for the replies! When I asked for geneotypes, I was not using the correct term for what I was after. I am actually looking for the possible alleles that can bind with the same locus point.

Not at all! You actually helped me realize that I was not asking for the right thing. I really appreciate your information, and I did visit your site before it was linked and find it VERY informative. I did see your lost of alleles, bit I thought there might be some more shared locus points.

I really am fascinated by all the combinations and how they present. I want to get a better understanding for it before considering breeding, as I would like to contribute to the future of ball pythons, not just breed to make baby snakes.
