    No pheno-genotype calculator? No problem

    Here's an alternative and a great way to learn how to use a punnett square to predict a cross's results. It may look a little intimidating at first but it's a matter of getting used to it. A better way would be to join TAS - you'll get our calculator for free during your membership period.

    He attacked everything in life with a mix of extraordinary genius and naive incompetence, and it was often difficult to tell which was which.

    I hope that you and Damon plan to run for re-election; I'd hate to see all your project efforts lose momentum.

    Here's an example that I did between 2 heterozygous Kois. The cross is represented as GgSS x GgSS


    G stands for Gm
    g stands for Gold
    S strands for Stripeless

    The resulting cross genotype ratios are represented by:

    Blue squares - Gold Blushings* (Sunset Blushings**)
    Green squares - Heterozygous Goldmarble Blushings* (Kois**)
    Red squares - Homozygous Goldmarble Blushings* (Kois**)

    * Phenotype generic names
    ** Phenotype trade names
