Best morph calculator

[paulh]

I went to WOBP and tried several matings.

Pinstripe x pinstripe. Both had a pinstripe mutant gene paired with a normal gene. IWOBP results were 1/4 normal, 1/4 pinstripe, and 1/2 pinstripe. The correct result is 1/4 normal (2 normal genes), 1/4 pinstripe (2 pinstripe genes), and 1/2 pinstripe (pinstripe mutant gene and normal gene).

I also tried a het albino x het albino mating. Results were 1/4 normal, 1/2 het albino and 1/4 albino. IMO, the correct results should have been 1/4 normal (2 normal genes), 1/2 het albino(normal-looking, albino mutant gene and normal gene) and 1/4 albino (2 albino genes).

IMO, there was no difficulty calculating hets. But there was considerable difficulty expressing the results. There was also the continuing belief that a heterozygous snake must look normal, which is false.

WOBP does not express heterozygote probabilities (66% probability het albino, 33% probability homozygous pinstripe). But that is okay. Doing it or not is a matter of choice.

I'm a bit confused by what you are saying. Top example should be 1/4 super pinstripe, which can be hard to ID but does look different, and the way you typed it here both sound exactly the same.

With albino example, those look exactly the same to me too. I guess what you are frustrated with is that it doesn't tell you which are phenotype? It's pretty much understood (with a few exceptions) when someone says "het X" it means its a visual normal or different morph, while being het for a recessive. Nobody calls a snake with one wild type one Pastel gene "het Pastel", it's just referred to as Pastel. The only exception I really see is acts-like-supers, I have seen people refer to Candino as het Albino het Candy, or in the case of incomplete dominants that are in the same complex and hard to tell apart like Asphalt/Yellowbelly, you might call the OS of a Freeway a "het Freeway" to express it's one or the other YB-complex morphs but you don't know which.

Good catch on the pastel x pastel mating results. WOBP results were 1/4 normal, 1/4 super pinstripe, and 1/2 pinstripe. And I should have written 1/4 super pinstripe (2 pinstripe genes) instead of 1/4 pinstripe (2 pinstripe genes). The difference between the WOBP and my results in both matings are that I included both genotypes and phenotypes rather than assuming that the reader would understand what was genotype and what was phenotype from the WOBP results.

Yes, I am extremely frustrated that the WOBP calculator does not provide both genotype and phenotype.

I follow the standard genetics definition of "heterozygous" at https://www.genome.gov/genetics-glossary/heterozygous. That definition is "heterozygous refers to having inherited different forms of a particular gene from each parent. A heterozygous genotype stands in contrast to a homozygous genotype, where an individual inherits identical forms of a particular gene from each parent." So a heterozygous gene pair could be a normal gene and an albino mutant gene, a normal gene and a mojave mutant gene, a normal gene and a pinstripe mutant gene, or a mojave mutant gene and a lesser mutant gene. There is nothing in the standard definition about a heterozygote needing to look normal. I am so frustrated with the misunderstanding of "heterozygous" that I seldom use it on these forums. I just name the genes in a gene pair.

"Acts like super" BARF! Kevin of NERD coined that and then abandoned it for "compound heterozygous". Everyone else should abandon "acts like super", too.

As for candino, I'd write "a candy mutant gene paired with an albino mutant gene". If I thought readers would understand, I might use "het candy/albino" or "a candy/albino gene pair" or "candy/albino". I would not use "het Albino het Candy" because that gives the impression that two gene pairs are involved.
