I created the following layered graphic using Sumopaint.  Each layer shows progression in completing a Punnett square.


  • I started with a question and an empty square.
  • Next, I wrote in the alleles that the male and female were contributing followed by the genotypes of the offspring in each square.
  • Finally I showed the probability of two heterozygous parents having offspring that are tongue rollers, or non tongue rollers.

It took me a fair amount of time and a critical youtube video to figure out how to layer using sumopaint.  I struggled mostly with the colors, if you notice in my last image, the word “tongue” is black and the other words are red.  I originally made a spelling mistake and when I went back to fix the mistake I couldn’t get the color to go back to red.  I’m sure there is a way, but I’ll admit that I just gave up after spending too much time trying to figure it out.

I could use something like this for my grade 9 science class, I could have them complete one step at a time on on paper and have this layered graphic on my smartboard to help guide them through the question.

    It’s so frustrating when something that should be so simple eludes us when it comes to text. I spent over an hour last week trying to change the output size of a pdf before I finally figured it out. I like your graphic, I can definitely see the progression.

    Hi Steve,

    Great use of layering. Did you look into the text box tool? That may make your text a little more appealing. Though I see you did play around with the writing tools which is great. Again, I like your consistency in your colour choices. Perhaps both parents could be different colours as well? The steps are nicely laid out in a neat and organized format.

    Good visual way to explain a concept. I think that Gimp or Inkscape are probably going to give a clearer path to working with your elements, but that will be within a much more complex interface. It’s one of those situations where a sufficiently large project motivates you to tackle the needed software. If you can get them, the Adobe tools are even more intuitive.
