Press R for Homozygous red, heterozygous blue- that means that both copies of the Red/blank gene are red, and only one copy of the blue/blank gene is blue- the other is blank. Press B for Homozygous blue, heterozygous blue- that means that both copies of the blue/blank gene are blue, and only one copy of the red/blank gene is red- the other is blank. Press E to return to heterozygous both- on each, there is one copy of the blue/blank gene that is blue, and one copy of the red/blank gene that is red. In order to switch between red being dominant and recessive over blank, press the left and right arrows. In order to switch between blue being dominant or recessive over blank, use (a) and (d). Up arrow to show Blue=dominant Red=dominant Punnett square, down to hide.
This is meant to simulate two dominant-recessive genes interacting, and to show that in a dragon. This was inspired by the albino and axanthic gene in hognose snakes, which are both recessive, which, when put together, create a snow hognose snake (in the same way that a red and blue gene put together make the dragon purple.) However, this is quite different, and it took me about 40 mins-1 hour fleshing out the concept
